I have some messy f77 code I'm translating to IDL. There is
one particularly messy routine which uses numerous forward goto's.
The code is in a do loop with several subsidiary do loops, each of
which includes at least one error or bounds checking procedure
implemented as a goto pointing at another block of code in the
outermost do loop. Finally in the event the error isn't reached
there are more forward goto's to skip over the error checking
code.
Actually that's just the base description. The reality is
worse. I am despairing of ever really understanding this code
sufficiently to rewrite it in IDL. However I could possibly
do a line by line translation if IDL had a goto operator or maybe
even a break operator for early exiting of loops. Near as I can tell
it doesn't have either. Can anyone provide any hints that might be
useful in translating messy f77 to IDL?
