Upgrading Cobol for MVS, VM, OS/390 and z/OS to IBM Enterprise COBOL Version 5 and higher requires some adjustment during migration.
Recent examples for parameter issues experienced:
"IGYOS4003-E Invalid option "RES" was found and discarded." - The RES or NORES option is not available with Enterprise COBOL.
"IGYOS4003-E Invalid option "TEST(NONE,SYM,SEP)" was found and discarded." - TEST(SOURCE) or TEST(SEPARATE,SOURCE) are new parm options
Release: All Supported Releases
After reviewing the Enterprise COBOL for z/OS Migration Guide for the particular parameter causing the error, update the parameter list being passed to the compiler.
For any other option, please have a look to Enterprise COBOL for z/OS Migration Guide.
