Use this keyword to identify the maintenance level of the module that failed.

Procedure: Perform the following.

1. Use the PTF number as the maintenance level keyword. The PTF number is found when you find the module identifier (see Step 2 in Module keyword).

2. Use the following process to find the PTF number if it is not available as part of the module identifier:
   1. If you are using preventive service tapes, you can identify the maintenance level of the last tape applied to the system.
   2. Find the maintenance level of a module by listing the SMP/E control data set (CDS).
   3. Find the name of the module that the previous steps identified as the cause of the problem, in the name column of the module entries.
   4. Find the replacement module identifier (RMID) field in the entry for the module. The RMID field contains the PTF number that identifies the maintenance level of the module. For the entire maintenance history of this module (superzaps, user modifications, and so forth), a LIST CD MOD with the keyword XREF and the module name produces a SYSMOD history of this module.
