SD is Bill Ackerman’s square-dance checker (the real Sd program).

This is Bill Ackerman’s real Sd. The square draws like Windows Sd (couples 1–4, red/green/blue/yellow, boys squares / girls circles, facing the pointed end). Pick a level, press Start, then type calls the way you would in Sdtty (for example heads start, then pass the ocean). After Start, two lists show what Sd says is legal from here: Concepts on the left, Calls on the right. Typing in the box shrinks both lists. Click a concept to add it (you can stack another), then click a call to do the whole line. You can still type and press Enter. Undo takes back the last call. The Command menu is the same idea as desktop Sd (Resolve, Write, Reconcile, …). The right side lists each call Sd actually ran (the full name, not a short abbreviation), with a tiny picture of the square after that call — click a picture to enlarge it, then Back up to here? if you want to undo back to that point. Resolve opens Sd’s two-box chooser: the getout on top, the search commands underneath. Up arrow recalls what you last typed. Leaving this tab idle for a while, or closing the page, stops Sd.
Press Start, then type a call — the dancers show up here.
Top box is the getout Sd is offering. Bottom box is Sd’s search commands. Say accept or next if the mic is on, or click one. Those keys are not dance calls, so they stay out of “Calls so far” until you accept.
Click a concept to add it to the line, then click a call to send it. Typing filters both lists. Long C4 lists only show a slice until you type.
Click a command line to copy it back into the calling box.

Type comment for this sequence, if desired.
Later calls stay on the right as “Coming up.” You can insert other calls, redo the next one, or try all of them to the end.
