IECIEPRM Parameter List z/OS DFSMS Installation Exits SC23-6850-01 |
|||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
The parameters passed to a Version 3 or Version 4 installation exit during label processing vary slightly among different types of exits. These differences, are noted in the "Description" column in Table 1. The parameter list is passed to the exit as an address in general purpose register 1; it is 32 bytes in length and is mapped by macro IECIEPRM beginning at DSECT IECIEPRM. Parameter fields not available to a particular exit are set to zero. The only fields allowed to be altered by an exit are the return code (IECIEXRC) and the user area (IECIEUSR); changing any other field has an unpredictable effect on system processing. A flag in the parameter list indicates which type of exit was entered.
