MFS Reversal utility

The MFS Reversal utility converts Message Format Services (MFS) control blocks back into IMS MFS utility control statements.

MFS Reversal utility overview
The MFS Reversal utility converts MFS MID, MOD, DIF, and DOF control blocks back into IMS MFS utility control statements. The MFS Reversal utility is helpful in cases where the MFS source files are lost or compromised.
