PROC statement

PROC is the first statement of each ACS routine. It identifies the ACS routine and which read-write variable the routine sets. You can precede the PROC statement with blank lines or comments, but not with other statements. For TSO CLIST coexistence, you can place a blank and then a number, such as 0 or 1, after the PROC statement. The number does not affect ACS language processing. To identify an ACS routine and the value it is to determine, you must specify a read-write variable at the end of the PROC statement. You must also place an END statement at the end of each ACS routine.

PROC <n> read-write variable

n is optional and can contain any numeric value.
read-write variable is a mandatory value that can be DATACLAS, STORCLAS, MGMTCLAS, or STORGRP. You can optionally precede the variable with an ampersand, &.

PROC 1 DATACLAS
PROC 0 &STORCLAS
PROC &MGMTCLAS
PROC STORGRP
