<p>The Change Routing Entry (CHGRTGE) command changes a routing entry in the specified subsystem description. The routing entry specifies the parameters used to start a routing step for a job. The associated subsystem can be active when the changes are made.

<li>The job associated with an active subsystem can only find objects that exist in the system auxiliary storage pool (ASP) or in a basic user ASP. Therefore, objects that are referenced by this command should exist in the system ASP or in a basic user ASP.

<p>Specifies the name and library of the program called as the first program run in the routing step. No parameters can be passed to the specified program. The program name can be either explicitly specified in the routing entry, or extracted from the routing data. If a program name is specified in a routing entry, selection of that routing entry results in the routing entry program being called (regardless of the program name passed in an EVOKE function). If the program specified in the EVOKE function is called, *RTGDTA must be specified. If the program does not exist when the routing entry is added or changed, a library qualifier must be specified because the qualified program name is kept in the subsystem description.

<h3>Maximum active routing steps (MAXACT)</h3>
|
||
|
|
<p>Specifies the maximum number of routing steps (jobs) that can be active at the same time through this routing entry. In a job, only one routing step is active at a time. When a subsystem is active and the maximum number of routing steps is reached, any subsequent attempt to start a routing step through this routing entry fails. The job that attempted to start the routing step is ended, and a message is sent by the subsystem to the job's log.
