SPECIAL CONSIDERATIONS FOR USING THE ZAP SERVICE PROGRAM Before you use the ZAP command against MODULE files, you can use the MODMAP command to determine whether a module map exists and what it
contains. When a ZAP input file has more than one pair of VER and REP control
records and a VER control record (other than the first) fails, you .ust
re.ove the records prior to the failing record and correct the error
before you issue the ZAP com.and again. Otherwise, the file being
.odified returns to its original status.
If you issue a REP control record against a file that
