AOF SUBSYS—Set Subsystem Identifier

The SUBSYS command sets the z/OS subsystem identifier (SSID) of the copy of CA OPS/MVS that processes subsequent ADDRESS AOF commands, and some REXX functions. These REXX functions include OPSVALUE and OPSPRM.

Use this command only if both of the following circumstances apply:

• You are running multiple copies of CA OPS/MVS.
• You want to address the commands to a copy of CA OPS/MVS that is not using the default SSID. The default SSID for CA OPS/MVS is OPSS.

This command sets the RC variable to zero, which means that the external data queue contains no output lines.

Consider the following information when you use the SUBSYS command:

• The only ADDRESS AOF commands that go to the specified SSID are those commands that are issued from the OPS/REXX program that issues the SUBSYS command. ADDRESS AOF commands that are issued from subsequent OPS/REXX programs go to other destinations.
• For OPS/REXX programs that run as part of a started task, the default SSID is the first four characters of the current step name.

  Note: This assumes that the first three characters of the SSID are OPS.

AOF SUBSYS has the following format:

ADDRESS AOF "SUBSYS keyword"

[sid]

SUBSYS

Identifies the subsystem where the copy of CA OPS/MVS that receives ADDRESS AOF commands is running.
