By using the command validity checker parameter on the RMVM (remove member) command you can copy the source member...
that is being deleted to a library (I have called 'OOPS') where it can be copied back into the library and file from which it was deleted. This has certainly saved a lot of time in needing to bring in backup tapes and restore file members from backup.
Code: PGM PARM(&P20 &P10)
DCL VAR(&P20) TYPE(*CHAR) LEN(20) DCL VAR(&P10) TYPE(*CHAR) LEN(10) DCL VAR(&FILE) TYPE(*CHAR) LEN(10) DCL VAR(&LIB) TYPE(*CHAR) LEN(10) DCL VAR(&MSG) TYPE(*CHAR) LEN(99) MONMSG MSGID(CPF0000) CHGVAR VAR(&FILE) VALUE(%SST(&P20 1 10)) CHGVAR VAR(&LIB) VALUE(%SST(&P20 11 10)) IF COND(&LIB *NE 'OOPS') THEN(DO) CPYSRCF FROMFILE(&LIB/&FILE) TOFILE(OOPS/MEMBERS) + FROMMBR(&P10)
