Version 32.5 changes

The missing CWSDPMI memory manager has been restored to the Windows 3.1/DOS version of the program. It is not needed for Windows 95, 98, or NT.

Sdtty now handles control-C correctly on Windows 95, 98, or NT. You can safely bind control-C to interlocked phantom columns, or whatever else you want. Typing control-C will not automatically stop the program. If you need to stop the program, type <break> or control-<break>, or use the task manager to perform an “end task” operation.

New concept: <anyone> in your Z.

It is now possible to enter fairly complex variations of plenty, with modifications to the star turns and similar things. For example, you can directly type [jay walk] and plenty, turn the star 3/4, interrupt before the star turns with [trade circulate]. For more complex variations, such as turning the star 3 but interrupting after the first 2, you still must use the “allow modifications” mechanism.

The program recognizes a few more resolves.

The program can now handle fractional stable and fractional twosome concepts on matrix calls. For example, from a completed DPT setup, you can call tandem 1/4 twosome belles shove off.

The call fold has been made legal for the ends, if they are as if leads in lines, from generalized diamonds or a “dog-bone” setup.

An embarrassing bug with the diamond concept was fixed. We apologize for any bogus cards that were created.

The interpretation of things like initially twice or random twice has been changed, in accordance with what appears to be the emerging consensus on this. The subject call is “flattened”. That is, initially twice mix has three parts—centers cross run, centers cross run, and centers trade. Initially as couples initially twice mix will do an as couples centers cross run, a normal centers cross run, and a normal centers trade.

[Note: the above was incorrect, and was removed in version 32.6.]

The usual number of radical changes were made in the internal mechanism of the program, making it more elegant, general, and powerful. The usual number of ad-hoc kludges were replaced with more powerful and general mechanisms. The particular areas revamped in this release were the “qualifiers” and “restrictions” in the database. The fractionalization mechanism was not changed this time.

Version 32.4 changes

It is once again possible to exit from a multiple-screen listing from “?” or “!” by pressing the “delete” key on a PC. You can also press “backspace” or the letter “q”.

Digits on the numeric keypad are treated the same as ordinary digits. Control, alt, and control-alt numeric keypad presses can be programmed as accelerator keys by using designators such as “cn3”, “an4”, or “can5”. See the manual for details.

A few bugs were fixed in the handling of heavily stacked concepts and meta-concepts.

Linear cycle from inverted lines is now done by the official Callerlab definition. The pass is right shoulders, but the final peel is in the direction of the original minwave.

There is a call easy does it (matrix) which allows 3x3 usage while compromising other aspects of the call.

There is a call recoil (matrix), permitted only from facing couples, which allows 3x3 usage while compromising other aspects of the call.

The usual number of radical changes were made in the internal mechanism of the program, making it more elegant, general, and powerful. The usual number of ad-hoc kludges were replaced with more powerful and general mechanisms. The particular areas revamped in this release were the inheritance mechanism (particularly relating to NxN modifiers and revert/reflect), the qualifiers to test general 1/4 tags, and, of course, the fractionalization mechanism.

Version 32.3 changes

An improper handling of screen erasure, scrolling, and cursor motion in the new Windows interface was fixed.

A possible error involving typing in comments under certain circumstances under Windows 95 may have been fixed.

The call mini busy now uses the really correct definition. For example, try split phantom waves explode and [mini busy] from 16-matrix offset columns. The call mini busy (matrix) was added, to allow the old non-canonical usage with concepts like single and 3x3.

A bug in the interaction of the echo concept and certain meta-concepts was fixed.

A bug causing occasional spurious “setups did not interact” warnings was fixed.

The bug allowing stretch finally twice scoot and weave (parts) was fixed.

Version 32.2 changes

Sdtty's interface with the Windows operating system has been rewritten. The program should be much more “system friendly” (and, we hope, “user-friendly”) than before. It no longer sets itself up in “full screen” mode. It operates in an ordinary window, that can be maximized, minimized, moved, and resized in the usual way. It also has scroll bars. It can also sense special key presses in a more flexible way.

Sdtty can respond to many more special key presses than before. In addition to the function keys, it can respond to letters and digits with the control and/or alt keys held down. It can also respond to “enhanced” keys such as the cursor arrow keys, “insert”, “delete” etc.

Sdtty now permits you to customize your special key presses in your initialization file. The file sample3.ini in the distribution has an example of this. It has an “[accelerators]” section followed by lines of the form

        key-specification     action

For example:

     al     split phantom lines
     cl     interlocked phantom lines
     cal    phantom lines

These three entries mean that alt-l will be a short cut for split phantom lines, control-l will be a short cut for interlocked phantom lines, and control-alt-l will be a short cut for phantom lines. A plus sign in front of a key specification means that it is to be used when starting, as in “+f1 heads start”, and an asterisk means that it is to be used when resolving, as in “*f12 find another”.

If you do not have an sd.ini file (for example, you have not copied sample3.ini to sd.ini), or if the file does not have an “[accelerators]” section, all of the standard key bindings will be used. If there is an “[accelerators]” section, whatever follows will replace all key bindings.

Refer to the manual for more details.

The following new options were added, to disable the various new features of the Sdtty user interface. You can place these in the “[options]” section of the initialization file.

        no_intensify
        no_sound
        no_color
        no_console

Refer to the manual for more details.

Sd has limited support for the fractal concept.

Sd can handle supercalls, as in finally clover and [right and left thru] or initially busy [finish turn the key].

There is a call <anyone> tie (parts) that can be used when the parts are required (for fractionalization, piecewise, initially, and so on.) It is like recycle (parts) or scoot and weave (parts) in that it doesn't have all that power of the base call, and should only be used when fractionalization is required.

Version 32.0 changes

There is a major new feature. It is now possible to “edit” sequences at any point. The way this is accomplished is through a “clipboard”. If you want to change your sequence at a point 5 calls back from the current point, you can move the last 5 calls to the clipboard. Then you can insert or delete calls in the usual way (by calling, or by using the undo last call command), and then move the clipboard back to the main sequence. See the “editing” section (section 7, page 34) of the manual.

You can use modifiers like 1x3 in front of the as couples or tandem concepts, or their twosome or fractional twosome veriants. In practice, a common way of expressing this to the dancers is with something like “one by tandems of three” or “threesome by one”.

New concepts: triple twin C/L/W of 3. These are done in a 3x6 formation, and form three virtual 2x3's. You can of course use mystic and invert mystic with them.

New concepts: center/outside triple twin C/L/W. These are done in a 4x6 formation, and form three virtual 2x4's. The center formation, or the two end formations, do the call.

New concepts: center/outside triple twin C/L/W of 3. These are done in a 3x6 formation, and form three virtual 2x3's. The center formation, or the two end formations, do the call.

New concept: center Z.

New concepts: twice removed, thrice removed.

New selectors: end boys, end girls, center boys, and center girls. These are intended for use with calls like ripple. If one of these selectors can identify the desired two people uniquely, it is probably preferable to use it instead of something like side girls or lead ends.

The [beau hop] an anchor but [[reflected flip your neighbor] and spread] bug was fixed.

The program has a vastly improved ability to handle differently oriented triple and quadruple columns, lines, waves, and diamonds.

The program has a vastly improved ability to handle Z's.

Many other minor improvements. We thank the callers at the 2nd USA West Convention for bringing up several interesting issues.

Version 31.98 changes

Many minor improvements. We thank the callers in the C2 hall at the 47th National Square Dance Convention for calling 3 things that can't be done by the program that they used, and for bringing up a number of interesting issues.

The triple Z's concept was added.

The calls rims/hubs trade back and rims/hubs trade <anything> now follow the definition really correctly. The original rims or hubs do the circulate or the other call. This now works correctly in columns, and things like yoyo rims trade [single shakedown] will work correctly in a tidal inverted line.

More generally, the mechanism for dealing with calls that involve the determination of the original centers, ends, or whatever (e.g. patch the <anyone> or rims trade back) is much more carefully worked out. For example, from columns, you can do a random tandem patch the centers. The original centers, before the tandem hinge and before the dancers were combined into tandems, will do the U-turn back at the end of the call.

A bug was fixed involving certain disconnected shape-changers in diamonds. For example, from a tidal wave, if the center 2 hinge, the program can now have various disconnected diamonds do things like flip the diamond.

Version 31.97 changes

Many minor improvements. We thank the usual anonymous sources for their many suggestions.

The space-invading version of <anyone> run the wheel has been renamed to <anyone> run the wheel (matrix). The call <anyone> run the wheel is a non-space-invading version that does not allow the various bizarre effects, but may be used with concepts like parallelogram

The designators very centers, very ends and all have been added. They are completely equivalent to center 2, outer 2, and everyone, respectively. Note that you very rarely need to say all or everyone. If you want everyone to press ahead, just say press ahead.

The handling of the disconnected concept has been expanded to handle the formulation in the Choreo Corner article in the June, 1998 issue of Zip Coder.

Version 31.96 changes

The program can now do shape-changers in triple formations that go to different orientations. From triple boxes with the center box oriented differently from the outer boxes, one can do things like triple boxes reach out or triple boxes follow to a diamond.

The program can recognize <anyone> lead for a <anycall> from a larger number of positions. Specifically, it recognizes “C1 phantom” setups and suitably populated 4x4 matrices that are in a promenade-like arrangement. You will be presumed to have told the dancers to promenade from that setup before the <anyone> lead.

New designator: outer 1x3s. This may be used to designate the outer lines or columns of 3 in such setups as an `H' or a diamond between two couples (heads circle the tag to a diamond.) You will often need to use the disconnected concept with this.

New call: plus <N>. Like with the flow, sweep 1/4, and similar calls, this uses rolling direction from the preceding call to tell it what to do. It might not be correct in all cases.

The triple columns concept was moved to C2 in accordance with a recent decision of the Callerlab challenge committee.

Version 31.95 changes

The program can handle mixed-orientation triple formations. For example, from a tidal wave, you can have the centers lockit, and then call triple waves switch to a diamond.

New concept: snag the <anyone>.

The code for snag and <anyone> work <concept> was overhauled. It should be much better at doing really obscure cases now. The special call snag circulate was removed. The snag concept simply does the right thing.

Version 31.94 changes

Many of the usual sorts of improvements were put in, in response to user requests. It is not possible to list all the ramifications of them, except to say that the program is less likely to refuse to do obscure things. It has a better understanding of call fractionalization and of where people are and how to put them back together.

The initially invert counteract bug was fixed. The stretch twist the line bug was fixed. The stretch dixie diamond bug was fixed. The own the boys (reach out ; concentric lockit) by touch and go 1/4 by [ah so] bug was fixed.

A rather obscure person-disappearance bug was fixed. An incredibly obscure (it required sextuple columns working right to provoke it) memory corruption bug was fixed.

The definition of regroup was changed in accordance with the recent Callerlab definition change. The ends are now permitted to be looking in.

New call: change the apex <M/4> x <N/4>. New concept: echo.

When one does split phantom columns zip code 1-1/2 from facing lines, so that the nothing in the center is done by phantoms, they sort of stay in a 2x2 box. A warning is printed, and the final setup is a 2x6.

New calls: 6 or 8 person here comes the judge or sock it to me. You may specify these with with 12 matrix/16 matrix, or with an explicit matrix size designator (e.g. 2x6 matrix), or with a concept that explicitly designates long lines (e.g. twin phantom lines of 6.)

New selector: those facing. Also, the funny concept, for certain calls such as slide thru, simply means those facing. So you can do funny slide thru large numbers of times. You must enter this as, for example, 9 times funny slide thru.

Version 31.93 changes

The parser is about 15 times faster on very difficult phrases, such as [[right and left thru] and roll] coordinate.

Because of an ambiguity, it was necessary to remove the “space invader” versions of right anchor <N/4> and left anchor <N/4>, when no person designator is given. If you want the “space invader” versions of these calls, you must use a person designator, even if that is everyone. Without a person designator, these are “breathing” calls that are suitable for use in distorted setups, as in trapezoid left anchor 3/4.

Version 31.92 changes

The unpleasantness of the parser in 31.91 has been fixed—you can type things like ping pong circulate directly.

Apostrophe and comma are optional.

You can get a u-turn back by typing u <space> <enter>.

The resolver is much more thorough in searching for single call resolves that give RLG, LA, or promenade endings.

The mechanism by which the resolver avoids presenting the same resolve twice sometimes mistakenly thought that it had already presented a resolve that it hadn't. As a consequence, the program occasionally missed a perfectly good resolve. This has been fixed.

You can type the call eight by as either eight by or 8 by.

You can now type in star modifications directly, as in chain reaction, turn the star 1/2 or chain reaction, don't turn the star (You may also use the simple modifications or allow modifications stuff, but you should hardly ever need to use those any more.)

For the call tag the star, you *must* type it directly. Do not type allow modifications and then tag the star the yellow brick road, expecting to be queried for modified star turns.

In text that Sd displays or writes out to the transcript file, the concepts twice, N times, and 1-M/N will be placed after the call. You still enter concepts, as before, in front of the call.

The spelling of wheel fan & cross thru has been changed to wheel fan and cross thru. We apologize for jerking people around, but this makes it consistent with all other “and” calls. There are now no calls with an ampersand in their names.

Version 31.91 changes

This is an interim release, fixing a few embarrassing bugs. Major functionality improvements that are being worked on are not yet in place. They will be coming out soon.

The function key control-F6 really, really, really gives the centers concept.

The definitions of scoot and weave and turn and weave were fixed to handle the turning motions correctly. We thank Kerry Hodnett for pointing out this problem.

The problem with outer 6 invert the column 1/3 was fixed.

For most calls with star turns, you can type a modification to the star turn amount directly. Say motivate, don't turn the star or motivate, turn the star 3/4. This doesn't yet work with tag the star. Also, if you want more esoteric things, like turn the star 3 but interrupt after 2 with a bias motivate, you still need to use the allow modifications mechanism.

There is a new section of the manual, “Interruptions and Interlace”, describing some esoteric aspects of calls like exchange the diamonds.

It is legal to omit the typing of apostrophe or comma. This means that you can type chain reaction turn the star 1/2 or ends go as you are turntable or lockers choice or "tag the star ers delight".

It is also legal to type a space where a hyphen would normally be required. This means that you can type "swing o late" or "tandem based triangles". Use this cautiously!! Because of word completion, Sd may complete more of the call than you were expecting when you type a space.

[The above problem was fixed in version 31.92.]

The calls triple scoot, partner tag, and remake the thar were moved from the Plus to the A1 lists, in accordance with the recent Callerlab resolution.

Version 31.90 changes

An enormous number of improvements were made, far too many to list here. Many are minor, many are significant. Most of these were made possible by analysis of C4 material generously provided by Lynette Bellini.

New call:

     cast a shadow, very centers cast 3/4

New concepts:

     REPLACE THE LAST PART
     INTERRUPT BEFORE THE LAST PART
     Y'S ARE SOLID
     Y-SOME
     Y's ARE SOLID N/4 Y-SOME
     Y-SOME N/4 SOLID

In the concepts BOXES/DIAMONDS/TRIANGLES WORK solid / N-some / fractional solid / fractional N-some, the word WORK has been changed to ARE. We realize that callers often use the word "work" in things like "triangles work solid 1/4 threesome", but this change makes the program's naming more consistent, and avoids any possibility of ambiguity. There is a meta-concept <ANYONE> WORK <concept>, that is essentially equivalent to "OWN the <ANYONE> for <concept> <call> BY <call>. We want to give the user complete and unambiguous control over which concept is used.

The calls that used the phrase "(by parts)" in their name have had that phrase changed to just "(parts)". Those calls are: recycle, cross cycle, scoot and weave, and couple up.

The program's interpretation of the splitting of a 2x4 for the concepts CENTRAL or CRAZY has been made more regular. The rule is that, if it is at all possible to divide the 2x4 into 2x2's, the program, and presumably the dancers, do so, even if such a division does not lead to the most common application of the call. The 2x4 is split into 1x4's only if the call is impossible in 2x2's. So, for example, 1/2 crazy switch to a diamond from parallel waves initially splits the setup into waves, as it has always done. The difference is in calls like tickle and the centers part of counter. On a 1/2 crazy tickle from parallel waves, the first action is done in each box, resulting in a tidal wave. then the centers do it again. On a central counter from parallel waves, each box does a cast off 3/4 followed by a lockit. On central interlocked counter or central cross counter, the initial division is into each wave, since the call is impossible otherwise.

The definition of crossfire has been changed so that the original ends can roll. The definition of this call does not involve an extend. It involves the original centers walking straight ahead to meet the original ends. Since the latter did not move forward, they do not lose their roll status from the cross fold.

The program can directly parse calls that take two subcalls in brackets, as in slant [swing thru] and [turn and deal] or [slip] the windmill, outsides [ramble].

Dixie grand is now a call, as well as being a recognized getout. After doing this call, the dancers will be in an alamo ring. You may need to give the pseudo-call adjust alamo to other pairing before doing the next call.

In Sdtty for PC's, function key control-F6 is a shortcut for the centers concept.

The call <anything> and the <anyone> roll re-evaluates people's positions before deciding who should roll. So, for example, if you say [swing thru] and the centers roll, it will be the new centers that will roll. You may need to make that clear to the dancers by saying something like the new centers roll

The program now understands the number zero. It can do things like take 0, loop and tag 0/4, 0 steps at a time, and track 0.

The word order reverse N/4 crazy is no longer accepted. It appears that some people believe that this word order is just a short notation for “reverse order N/4 crazy.” If you want reverse order N/4 crazy, say so. If you want N/4 reverse crazy, say so.

Version 31.89 changes

The program can do singing call progressions. There are two new commands, available only at the start of a sequence (that is, when you could say heads start):

     toggle singing call
     toggle reverse singing call

The "reverse" singing call option chooses a reverse ("right hand lady") progression.

It has a much more sophisticated way of checking for getouts, and can see many more of them than previously.

It has an improved understanding of how 12 matrix, 16 matrix, 3x3, and 4x4 interact.

Plus several dozen minor improvements in the database, the program's awareness of where people are, and so on.

Version 31.88 changes

The changes described below (for version 31.87) for percolate (centers and ends) and cover up (centers and ends) were added for perk up (centers and ends) as well.

An error in sidetrack from a 1x8 column was fixed.

Version 31.87 changes

When the <anyone> work concept is used, as in boys work tandem swing thru, the program will put in the word all, along with a comma. It will come out like boys work tandem, all swing thru. You do not type in the comma or the word all.

Some of the obscure nuances of countershake, like 3x3 countershake from a 2x6 matrix, have been dealt with by creating a call countershake (matrix). The default call (without the word matrix) is completely fractionalizable. See the manual for details.

Cover up and percolate can be used with the central concept from some formations. The calls cover up (centers and ends) and percolate (centers and ends) have been created for this purpose. See the manual for details.

The call "scoot and counter", if done from a left-handed 1/4 tag, will have the outsides use a right hand at the end. This appears to be somewhat more in keeping with common usage than using a left hand, though the situation is not really clear. The Callerlab definition still prohibits this, and Sd did prior to this release. You were always permitted to say "left scoot and counter", and this is still permitted.

The "anchor the <anyone>" concept has been improved to handle 2-person calls in a more general way. It should now handle all 2 and 4 person calls.

Version 31.85 changes

There is a rudimentary understanding of the "anchor the <anyone>" concept.

The handling of fractional, interruptible, crazy, random, initially, and finally has been completely revamped. The program has a much simpler and more logical internal structure now. It should do a much better job of handling things like "random finish 2/3 reverse order hot foot spin".

The program has a much better understanding of the individual "O" circulates that the outsides do on a "hocus pocus". However, you must use the special call "hocus pocus (fractions)" to get this. See the discussion in the manual.

The definition of "crossfire" has been changed to bring it up to date with the nuances of this call.

It was discovered that the program had been cheating on "change the web", turning the star only one position instead of the five positions that the definition mandates. This shocking and scandalous situation has been rectified.

Version 31.84 changes

The mechanism for deciding when to step to a wave or rear back from one has been improved, hopefully making it better able to reflect the way real dancers think about this issue.

The level "c4x" has been added, and the interpretation of level "c3x" has been changed. These levels are for calls that might not be considered really legitimate, but that are nevertheless used. In the case of c3x, these calls are not on the official list. In the case of c4x, these calls don't appear to be commonly used, according to informal lists.

It is generally NOT NECESSARY to run the program at either of these levels. When you run at c3, c3x calls may be used. When you run at c4, c4x calls may be used. Whenever such a call is used, a warning is printed. (If you explicitly run the program at c3x or c4x, you may use the calls without getting a warning.)

Examples of c3x calls are:

     <ATC> nuclear reaction
     change lanes
     <anyone> run the wheel
     snake
     trixie
     settle back
     hang loose

Examples of c4x calls are:

     disperse
     mayday
     loop the loop
     trap it

The above lists are intended to be illustrative, not exhaustive.

Version 31.83 changes

A number of questionable or controversial calls now print warnings when they are used. For example, explode the line from a 2-faced line is marked as a violation of the definition of the call.

New concepts:

     as couples in a 1/4 tag
     as couples in a 3/4 tag
     as couples in a 1/4 line
     as couples in a 3/4 line

A number of minor bugs and inconveniences were fixed.

Version 31.82 changes

There is added detail in the manual describing subtleties of <anyone> start and initially <anyone>. Please see the section “Anyone Start”, at approximately page 90.

A number of minor improvements were made in various calls, such as:

        Load the Boat (can be done from inverted lines)
        Rip the Line (allow T-boned centers)
        [Cross] Pair the Line (allow T-boned centers)
        Explode and Reverse Explode (follow Callerlab definitions better)

The behavior of the "cross concentric" concept has been modified slightly to bring it into conformance with modern usage. When a cross concentric call takes a 1x4 to a 2x2 (e.g. recycle), the original center 1x4 will elongate their final 2x2 on the outside perpendicular to *THEIR OWN* original 1x4 axis, not the elongation of the entire setup. The difference arises when the setup is a wave between two miniwaves (e.g. centers lockit from a tidal wave). A cross concentric recycle will have the original centers elongate perpendicular to their original center wave. The resulting setup will be a "split square thru" type of setup. See the excellent article on this topic in the April 1996 issue of the Zip Coder magazine.

Some people do not agree with this. In fact, it is contrary to an example diagram in the Callerlab C2 definitions, though the text of those definitions is not clear as to whether elongation is being measured relative to the whole setup or just the centers or ends.

When this different behavior occurs, the program will print a warning:

        "New ends should opt for setup perpendicular to their original (center)
        line.  Beware:  This may be controversial."

Proceed with caution in this area. If you do not agree with this, do not use it. If you require the old behavior, enter a "stable concentric quarter right" after the cross concentric call to move the outsides to the other position.

Version 31.81 changes

IMPORTANT NOTICE IMPORTANT NOTICE IMPORTANT NOTICE

The word "<concept>" has been removed from the names of the two concepts:

        do the <Nth> part                and
        <anyone> work

You just type them that way, as in:

        centers work tandem acey deucey     or
        do the 2nd part tandem remake

They will be printed in the transcript the same as before:

        centers work tandem, acey deucey    or
        do the 2nd part tandem, remake

The difference is that you NEVER type the word "<concept>".

New designators:

        lead ends
        lead centers
        trailing ends
        trailing centers

These can be used, for example, to designate people for calls like "ripple".

The program is much better at handling various types of perpendicular 1x2 setups of the sort that arise in fractional exchange the diamonds or fractional ripples. For example, it can do "<so-and-so> ripple 2-1/2" from a parallelogram.

Version 31.80 changes

The handling of Quarter the Deucey, Spin Chain the Star, and variants thereof has been changed. After the first part, the end looking out has only one remaining part, which is a circulate to the other end of the wave. This person formerly did two parts – a half circulate as if in a Relay the Top, and then the other half of the circulate. This makes a difference if "Finally Stable" is used. The correct ending position for "Finally Stable Quarter the Deucey" has both ends facing out, as if in lines. We thank Dave Hodson and Leon Eskenazi for pointing out this problem.

Version 31.78 changes

Various problems in the parser changes of version 31.77 were fixed.

The bug arising from the line "sequence <filename>" in the "options" section of the initialization file was fixed.

A number of improvements have been made in "ladies chain" types of calls. All 4 ladies chain N/4 (from a squared set) has been added, along with head/side ladies chain to the right and head/side ladies chain 3/4. See the section “Up to the Middle” in the manual.

The call "<ANYONE> cloverleaf while the others <ANYTHING>" has been added, and is at Mainstream. It attempts to capture some of the common uses of this figure. It is in many cases identical to the A1 call "clover and <ANYTHING>".

The calls "and 1/4 more" and "and 1/2 more" were moved to Mainstream to capture such things as the "courtesy turn full around" usage.

Version 31.77 changes

There is a *MAJOR* improvement in the parser. (That's the part of the program that analyzes the line that you type and figures out the logical structure of what you are trying to say.) All the calls that have "<ANYTHING>" in them, like "clover and <ANYTHING>", the ones that print out with brackets around the "<ANYTHING>" calls, can now be typed in directly. You just type clover and [swap around] or [follow your neighbor] and spread or catch [2/3 recycle] 3 or [shakedown] and roll or clover and [3/4 stable left catch [[reflected flip your neighbor] and spread] 3] or whatever you have in mind. (Good luck calling that last one!)

THE BRACKETS ARE NECESSARY!!! Without them, it would be impossible to distinguish between

              clover and [[swap around] and roll]
     and
              [clover and [swap around]] and roll

The calls like "trade motivate" (a modified version of the circulate for calls that start with a circulate) have had their name changed in the menus. They are now "<ANYCIRC> motivate". There are also calls "<ANYTHING> motivate" (along with their more mundane friends like "clover and <ANYTHING>" and "<ANYTHING> and spread". The former calls are entered, as before, without brackets: Just type in roll perk up or whatever. The latter are entered with brackets. Type [2/3 recycle] motivate or clover and [swap around] or whatever. Because both types of calls can be typed directly, there is hardly ever any need to type words like "<ANYTHING>" or "<ANYCIRC>". However, we thought you'd like to know that we have changed the names to avoid any ambiguity.

Version 31.76 changes

The "straight" and "twisted" concepts are implemented. Of course, "straight" things have existed on a case-by-case basis for some time, but now you can say, for example, "straight yoyo crossfire" instead of "yoyo straight fire" if you wish.

Version 31.75 changes

The program has a significantly improved notion of how to do the call squeeze.

Version 31.73 changes

The program's ability to handle calls in alamo rings is somewhat improved. See the discussion of the call adjust alamo to other pairing under “Call Notes” in the manual.

The concept formerly called diagonal has been changed to diagonal box in accordance with current usage.

The call ... and spread is obsolete. Just use spread, for both the follow your neighbor type and the heads star thru type. There are also calls <anything> and spread and <anything> and the <anyone> spread. Use the latter to have specified adjacent people spread, after, for example, a motivate.

Version 31.72 changes

*********************************************************

IMPORTANT NOTICE IMPORTANT NOTICE IMPORTANT NOTICE

Version 31.72 behaves differently from previous versions. If an error occurs on a call/concept combination (for example, you type triple boxes switch the wave), the concept and call will both be discarded. Previously, the concept (triple boxes) remained in place. You would have had to type undo if you wanted to get rid of the concept.

The old behavior was misguided and horrible. If you are accustomed to typing undo after an error involving a concept, you may find the change disconcerting, since undo will now delete the entire previous line. You should either get accustomed to the new behavior as soon as possible, or follow the directions below for making the program use the old behavior. This involves either typing the command toggle retain after error when the program starts, or putting the line retain_after_error in the [Options] section of your sd.ini file.

*********************************************************

The operation of ignoring blanks (previously set with the ignoreblanks line in the sd.ini file or in the command line) is now controlled with a toggle command. The command is

     toggle ignoreblanks

It is normally off. It can still be turned on automatically at program startup, as before, through the sd.ini file or the command line. See the reference manual for further details.

The operation of discarding or retaining entered concepts after an error occurs (previously set with the discard_after_error line in the sd.ini file or in the command line) is now controlled with a toggle command. The command is

     toggle retain after error

The name of this has been changed from discard to retain. It is still normally off, but that means that the program normally discards, rather than retaining. Hence, the default behavior has changed. In the absence of any special action, the program will DISCARD entered concepts. Previously, it retained them. To get the old behavior, that is, to retain entered concepts, you must use the toggle retain after error command. It can also be turned on automatically at program startup, through the sd.ini file or the command line. The line in the [options] section of sd.ini file to do this is retain_after_error. The command line switch is -retain_after_error. The old command discard_after_error are maintained for compatibility, but they have no effect. See the reference manual for further details.
