the best helper is certainly the manual it will tell You why it happens, and hint on how to fix it
cheers enrico When I tell somebody to RTFM or STFW I usually have the page open in another tab/window of my browser, so that I am sure that the information requested can be reached with a very small effort
I'm not sure what you mean by "all of a sudden". Do you mean previously all was OK, and now not? Then something has changed which has caused the problem.
Look up the 93 in the Cobol manual (section 6.1.8.9.1, Enterprise Cobol, v3 r1).
You'll have to check the other messages in your JES output.
