Most of my endless loops occur when I make programming
errors in my CATCH error handlers. :-( So my favorite
way to get out of them is:
CATCH, /CANCEL
as the FIRST line of every CATCH error handling routine I
write.
This is followed closely by CTRL-ALT-DELETE. :-)
CTRL-C doesn't usually work because most loops are
a single command to the IDL compiler and IDL doesn't
check for interrupts until the end of each command it
executes.
Cheers,
David
