Converting MFS control blocks to control statements

To convert MFS control blocks (MIDs, MODs, DIFs, and DOFs) back into the IMS™ MFS utility control statements or to copy MFS control blocks by using the MFS Reversal utility, you must prepare JCL for MFS Reversal and submit the job.

About this task

Sample JCL for the MFS Reversal utility is in the SHPSJCL0 library, member FABVIVP. You can modify this sample JCL and then use it to run the utility.

Procedure

  1. In the MFS Reversal JCL, code the EXEC statement and DD statements.

    See JCL requirements for the MFS Reversal utility.

  2. In the SYSIN data set, code the control statements for the MFS Reversal utility.

    See Control statements for the MFS Reversal utility.

  3. Submit the job.
  4. Check the output data sets that are generated.

    See Output from the MFS Reversal utility.

What to do next

The MFS Reversal utility makes certain assumptions when generating source. You might need to modify the generated source before you use the source as input to the MFS Language utility. See Important notes about the generated source for information about the generated source.
