Changing the Default SORT and MERGE Operations

Problem:

Is it possible to change the SORT/MERGE operation to a 3rd party?

Resolution:

The compiler directive CALLSORT defines the program to be called to handle all SORT/MERGE operations.  The syntax is as follows:

     CALLSORT "sort-name"

"sort-name" is the root-name of a program to be called to process sorts and merges.  The default is - CALLSORT"EXTSM"
