Hello,
I'm looking for information about problems that could occur in production
with Cobol programs and that could generate abend. I would like to find a
description and how to prevent them before they occur.
For instance, I think that it could be interesting to avoid moving
alphanumeric variables into numeric variable without checking them by using
a IF NUMERIC or moving data into another that is shorter or avoid closing
file or never check array boundaries...
Do you see other important cases related to performance or robustness?
Thanks in advance.

You could use LE condition handling to trap errors and
handle them in some installation-specified standard
way. In our course "Enterprise COBOL Update I: Essentials"
we have a lab that builds and uses a condition handler
to intercept most errors; the classroom version just
lets the program continue; in real life, of course, you
would take more severe actions. But at least we demo how
to intercept and analyze conditions that arise. Check out
