CHAPTER 4
DEFINING JOBS
This chapter tells you how you set up jobs on your computer. A "job" is a "workplace" in
memory that has a name for identification purposes, and has a terminal attached to it.
4.1DISPLAYING THE INITIALIZATION FILE ON BOOTUP (:T)
The first line in a system initialization command file is usually :T. This tells the monitor
to display the system initialization command file on a terminal as it is processing.
When the monitor first finds the system initialization command file, the process of
reading and processing the file is initially under control of the first job defined (to which
no terminal has yet been attached). As soon as a terminal is defined (by the first
TRMDEF command), the monitor displays the rest of the system initialization command
file on that terminal screen as it executes the file.
If you don’t want the monitor to display the system initialization command file as it
processes it, replace the :T with :S. If you only wish to see error messages if they
appear, or FORCEd program input, replace the :T with a :R.
The semicolons in the examples indicate comment lines. The monitor does not process
comment lines, but does display them as it processes the system initialization command
file.
4.2DEFINING THE MAXIMUM NUMBER OF JOBS (JOBS)
The JOBS command tells the monitor how many jobs to allocate on the computer. This
defines how many entries are made in the job table within the system monitor.
You must always specify at least one job to complete the system initialization process.
This first job is used to execute the remainder of the system initialization command file.
We call this the "Operator Job."
You may allocate as many jobs as you wish with the JOBS command, though it can be
wasteful of memory if you define many more jobs than you need. Each job you specify
will cause four bytes of memory to be reserved within the monitor area of memory. No
additional space is used until a job is named by using the JOBALC command.
