IGZCUST
IGZCUST is a routine that processes the UNSTRING verb. When your program uses the UNSTRING verb this subroutine is invoked.
The UNSTRING verb can be used to substitute for several MOVE statements. UNSTRING causes contiguous data in a sending field to be separated and placed into multiple receiving fields.
Hints
If CPU time IGZCUST is high, use individual MOVE statements where possible. They use less CPU than the UNSTRING verb.
