The REXX Password Exit
In z/OS R9, a new system component called System REXX (SYSREXX) was introduced. SYSREXX provides the ability for REXX execs to be executed outside of conventional TSO/E and batch environments. SYSREXX was a web deliverable on R8 and first appeared in the base in R9.
In z/OS R9, RACF provided a new password phrase exit (ICHPWX11) sample which utilizes SYSREXX in order to call a REXX exec named IRRPHREX, in which password phrase quality rules can be coded.
What this download provides is a similar capability for the new password exit, ICHPWX01. A sample ICHPWX01 assembler module is provided, as well as a REXX exec IRRPWREX which it calls. Once you have modified ICHPWX01 to your liking and install it, then subsequent changes made to IRRPWREX will not require an IPL to take effect.
