The new-password-phrase exit must be named ICHPWX11.

Code the ICHPWX11 exit to be reentrant. It can have any RMODE but should use AMODE(31) or AMODE(ANY) for the best use of virtual storage and best RACF® performance.

The exit can run in the RACF subsystem address space. For more information, see Exits running in the RACF subsystem address space.
