Hello. 
Unidata 6.0.8
AIX 5.1

One of our programmers asked this question:
If I have this:

COMMAND = 'PROGRAM.A'
EXECUTE COMMAND CAPTRURING OUTPUT

Is there any way for 'PROGRAM.A' to sense that it is in capturing output 
and stop the capture?

What we have is a case where an open file error may occur and we need to 
have the user go back into a menu, but we do not want them to see the 
error. Problem is that the error is waiting for user input to continue and 
user thinks the session is hung up or locked, or they start hitting 
returns and log themselves off. If we can tell we are in capturing output, 
we can force the session to end the capture and return to a menu.

Thanks!
