MFSEXITS= parameter for procedures

Use the MFSEXITS=segment-exitnum parameter in procedure to specify the lowest-numbered MFS Segment Edit exit routine to be loaded by IMS.

segment-exitnum must be a decimal number less than or equal to 127. It must also be greater than the default or specified value for the MFSEXITF=field-exitnum keyword parameter. If MFSEXITS is not greater than MFSEXITF, then IMS issues DFS1920I and sets defaults for both keywords. The default is 127.

The IMS-supplied MFS Field Edit exit routine DFSME127 is always loaded. For example, an MFSEXITS=120 specification indicates that the user-supplied MFS Segment Edit exit routines DFSME120 through DFSME126, and the IMS-supplied DFSME127, are loaded by the IMS system. The user-supplied exit routines must be placed in an authorized library in the JOBLIB, STEPLIB, or LINKLIST library concatenated in front of the IMS.SDFSRESL. If any exits cannot be loaded, then IMS will issue message DFS1934E for each exit that could not be loaded.
