Planning to modify compiler option default values
IBM provides a default setting for each compiler option. You can accept the IBM®-supplied compiler option values when you install Enterprise COBOL, or you can modify them to better suit the needs of programmers at your location. You can also choose whether your application programmers will have the ability to override an option default (meaning the option default is not fixed) or will be restricted from overriding an option default (meaning the option default is fixed). The IGYCDOPT program lets you set and fix the defaults for the compiler options.
Compiler option defaults is set in the IGYCDOPT program.
IGYCDOPT is link-edited with AMODE 31 and RMODE ANY during installation.
When you assemble COBOL customization parts, such as IGYCDOPT, you need access to a system MACLIB. Typically, the MACLIB is found in SYS1.MACLIB. You also need access to the COBOL MACLIB IGY.V6R3M0.SIGYMAC.
