information of remote processes, device-information requests, and traffic statistics.

Expand Manager Process ($ZEXP)
The Expand manager process, $ZEXP, provides the interface between the Expand
subsystem and the Subsystem Control Point (SCP). The Expand manager process
must be started and named $ZEXP. SCP is the managing process for the Subsystem
Control Facility (SCF). The Expand manager process directs SCF commands to the
appropriate Expand line-handler process and forwards responses from Expand line-
handler processes to the appropriate user.
Note. The SCF interface to the Expand subsystem is described in Section 14, Subsystem
Control Facility (SCF) Commands.
