Input Action

To activate any job requiring the use of unit record devices, a command of the following format must be entered:

Command:
ZAURS XXXX ---

Where: XXXX = Name of the unit record job to be activated.

The System Message Processor (03-CSMP) recognizes the AURS code and passes control to the Unit Record Message Editor (03-CUAE). There is a high priority job table and a low priority job table within the Unit Record Message Editor. The first table contains jobs that can be activated no matter what the system activity level is; whereas the second table contains jobs that can be activated only if the system activity level test is satisfied. The test is a comparison between the number of currently available 128 byte core blocks and the system defined level of 128 byte core blocks that the CREXC macro checks to see if an entry can be introduced into the system. Upon receiving control, the Unit Record Message Editor searches through its job tables for the unit record job name specified in the input message. If the job name is in the high priority job table, the appropriate program is entered to perform the task. If the job name is found in the low priority job table, the system activity level test mentioned above is performed. If the system activity is low enough to initiate the job, the proper program is activated. Otherwise a message is sent to the originating terminal informing the operator of the high level of system activity and the entry is terminated. The operator should re-issue the command at a later time to get the job started.
