IBM® provides you with tools to verify symbol usage in parmlib. The parmlib symbolic preprocessor tool allows you to test symbol definitions before you IPL the system to use them. This tool shows how a parmlib member will appear after the system performs symbolic substitution. For information about setting up and using the parmlib symbolic preprocessor tool, see Symbolic Parmlib Parser.
If you only need to verify a new parmlib member's use of the current system symbols, you can run the IEASYMCK sample program to see how the contents of the parmlib member will appear after symbolic substitution occurs.
IEASYMCK is located in SYS1.SAMPLIB. See the program prolog for details.
