Major call 4
The EFS program provides any final user-written messages for printing to the message data set.
At Major Call 4, DFSORT supplies your EFS program with fields in
the EFS interface containing:
- An action code indicating that Major Call 4 is in effect.
- An EFS Program Context Area (a private communication area for the EFS program).
When the EFS program returns control to DFSORT, it can supply fields
in the EFS interface containing:
- A message list containing messages for printing to the message data set.
- A return code (in general register 15).
