IGZERRE
IGZERRE is a COBOL library routine that allows a non-COBOL program to initialize the COBOL run-time environment. Calling IGZERRE improves performance because the environment is not terminated and rebuilt each time a COBOL program is invoked from a non-COBOL main program. Using a STOP RUN returns control to the caller of the routine that invoked the IGZERRE initialization.
Hints
Use IGZERRE when the initial program called is not a COBOL program. IGZERRE is similar to the COBOL run-time option RTEREUS. See the references below for details on the COBOL run-time environment.
