If the problem is in the DFSMSrmm ISPF dialog, use the ISPF log to determine the failing module name by performing these steps:

1. Examine the ISPF log to locate an entry that indicates the abend.
2. If the entry contains a module name, for example EDGRDDIS, record the module name for your module keyword and continue with Building modifier keyword strings. Your keyword string would look like this:

   Keyword string so far: 5650DF186 R210 ABEND0C1 EDGRDDIS

   If you cannot determine the module name from the ISPF log, continue with Building modifier keyword strings.
