System Control File
Preparing the CP System Control File (DMKSYS) The CP system control file consists of macros that describe the CP system residence device, the system storage size, the CP-owned direct
access devices, the system operator's user identification, the system
timer value, the system pointer variables, automatic performance
monitoring parameters, and security journaling parameters. The
installation is responsible for ensuring the presence and accuracy of
the macros described below.

1. Samples of the DMKSYS and DMKSNT files are provided with the
starter system. If you use these, you can save the eMS system at
the end of the system generation procedure. VM/310 prompts you to
tell it if you want the sample DMKSYS file punched. You may modify
this file if you wish. For example, you could modify the starter
system DMKSYS file to add other CP-owned volumes.
2. SYSLOCS must always be the last macro coded.
The DMKSYS module supplied with the 2314 starter system is: DMKSYS CSECT SYSOWN (VMRELn
