Will,

Two things.

First, good programming practice tells you to define the abort logic once.
Sure G # H is simple, but this is just an example it could get quite
complex.

Second, There are statements before and after the abort situation, and your
code doesn't handle it.

You don't need a DONE.FLAG
  A1 = 0
  LOOP UNTIL (G=H) OR (A1=X) DO
     A1 += 1; A2 = 0
     LOOP UNTIL (G=H) OR (A2=Y) DO
        A2 += 1
        You're in a maze of twisty little passages all alike
     REPEAT
  REPEAT

 I have no idea what you mean, they both "abort" if you want to call it hat.
 They both exit the loop on the exact same condition, at the exact same
oment.
 I don't see the distinction you're trying to draw

ill,
his type of logic is a common practice when you can have an Abort situation
the middle of processing data.
ou are correct in your examples they are the same.  But that is not the int
here.  You must remember that we are in two FOR..NEXT loops with ssible
1000s or 10,000s loops.  If we are processing and suddenly a esource oes
off-line, then we need to abort the process.  My construct is  great ay of
handling the abort.
our way doesn't work because the values of G or H can change if you just ep
looping on your FOR...NEXT loops.  The original poster wanted to EXIT t, and
stop processing.

  Loop
 until done.flag do
 repeat
  is the same as
 Loop
 until (a=b) do
 repeat
 You don't need a done.flag in this case -----Original Message-----

program to gracefully exit out without having to go u frivolous loops.
