IGZ0012S   There was an invalid attempt to end a sort or merge.

A sort or merge initiated by a COBOL program was in progress and one of the following was attempted:

1. A STOP RUN was issued.
2. A GOBACK or an EXIT PROGRAM was issued within the input procedure or the output procedure of the COBOL program that initiated the sort or merge. Note that the GOBACK and EXIT PROGRAM statements are allowed in a program called by an input procedure or an output procedure.
3. A user handler associated with the program that initiated the sort or merge moved the condition handler resume cursor and resumed the application.
