Re: U2 hide error

The immediate problem is "JM 2.UNHIDE:01-07Q2 ". The correct usage is JM
2.UNHIDEQ2 . Unlike frame HIDE:*, the nomenclature of frame UNHIDE does
NOT support the appendage of Save/Get numbers after a colon -- because
there is no need for it. UNHIDE simply restores the entire set of S/G
values saved with the last HIDE statement -- a last-in, first-out
operation, as Robert points out. "UNHIDE:01-07", not matching any
framename spec in U2, generates a frame-not-found "application error" (or
a default to the catchall trapname frame {{5*}} ); frame UNHIDE is not
executed and no UNHIDEing occurs. Hence the lowercase "a" in S/G 05 was
not being restored.

YES! Thanks, Carl. Maybe a warning to that effect in the .INF file would be
prudent (correct syntax for UNHIDE is in there, but quietly).

I changed about 5 different UNHIDE:nn-mm to UNHIDE. They were a trap lying
in wait. This saved hours of under-pressure searching for errors--whew!
