You are absolutely correct, and thank you for pointing that out. That's
Jim's code, not mine, so I didn't recognize it; I was on a hair-trigger
for __gg__check_fatal_exception, which is part of the massive burr under
our saddle for the last month or so.
Iain, feel free to do what you need to do. And if somebody wants to let
us know what we should use instead, I am sure Jim will be all ears. That
external reference is used to pick up the name of the executable for entry
into the syslog when a COBOL error condition is set. Obviously in a Linux
system we'd like that, or the equivalent. But there must be ways of
picking up the information needed for a useful log entry.
Thank you.
