How can this structure be cleaned-up?
begin case
case Ans = 'A' ; gosub Check.A
case Ans = 'B' ; gosub Check.B
case Ans = '2' ; gosub Check.B
end case
The following is more difficult to read.
begin case
case Ans = 'A' ; gosub
, but that's a matter of personal
preference.

If this is all you need, why not:
IF (Ans = 'A')
Try this
ON index('AB2',Ans,1) GOSUB Check.A, Check.B, Check.B

Hi Bill,
Unlike languages such as C, Basic does not allow multiple conditions in the
way in which you are looking to do. In terms of run time performance or
program size, if it really is just a GOSUB, there whould be little
disadvantage in writing the more verbose form of your first example.

begin case
case Ans = 'A' ; gosub Check.A
case Ans = 'B' ; gosub Check.B
The first structure emphasizes program flow based on Ans and is very
readable. The second structure show program branching and is also readable.
Another approach might be thus:
Alpha.Cmds=
Alpha.Cmds1, -1 = A
Beta.Cmds =
Beta.Cmds1, -1 = B
Beta.Cmds1, -1 = 2

Not good if answer is not limited to one character wide.
Isn't ON GOSUB out of style?

Just to be different...
Why not add a new label called Check.2 put it right before the label
Check.B
Then the code would look like:
begin case
case Ans = 'A' ; gosub Check.A
case Ans = 'B' ; gosub Check.B
case Ans = '2' ; gosub

Execution should flow top to bottom, not left to right, from a
comprehension viewpoint.
Comprehension contributes to Maintainability, the premiere attribute of
software quality.
Along same lines, each case block should test the same sort of thing.

Hi Karen
I've seen this used in after prompt subroutines, where there were literally
multiple hundreds of Subroutines to execute, based on the attr number. In
that case it's cleaner, and might I add easier, than HUNDREDS of lines of
code that just say
CASE ATTR = 1
GOSUB 1
SNIP 400 LINES OF
20 matches
