True, but there are so many other reasons why code that old should have
already been migrated and re-compiled on a newer COBOL compiler sometime
in the last three decades. If you've got many OS/VS COBOL load modules
still lying around you've potentially got so many other problems:
inability to implement changes/corrections to that code for decades,
uncertainty over source/load-module consistency, limited exploitation of
virtual memory > 16 MiB, object code that does not exploit machine
instruction enhancements of last several decades, possibly even some
unresolved Y2K issues.
Perhaps Enterprise COBOL may force the issue in some cases, but if a
shop has lacked the ability to compile and regenerate a module for 25
years, perhaps it's time they were nudged.
