Often a new release of z/OS® includes new statements or parameters for the HZSPRMxx parmlib member. For example, the HZSPDATA statement in HZSPRMxx is new for z/OS V2R1. How does this work if you share HZSPRMxx between systems at different levels? The answer is, it should work fine. Even if you exploit all the new parameters and statements that come down the pike, IBM® Health Checker for z/OS simply issues a syntax error message for unsupported statements but processes all the other statements in the HZSPRMxx member.
