Internal Diagnose Codes

The ACF command SRF and most other CMS-based CA ACF2 for z/ VM programs use diagnose codes ACF2 and 0ACF to communicate with code running in CP. CA ACF2 for z/ VM has built-in protection for these codes. We recommend that you do not limit them. For example, SRF applications cannot perform validations or modify database records unless the user has the appropriate authorization. However, if you code an INCLUDE ALL in the DIAGLIM VMO record, be sure to write a rule allowing for both the ACF2 and 0ACF diagnoses.
