CHAPTER 5
Background Processing
NBSpool’s background processing capability is another, very powerful feature of this product.
Certain commands or groups of commands may be executed repetitively as a background task.
Background processing is available through two methods

a background job that invokes
NBSpool and its
XEQ
command, or
SPOOLCMD
files that contain NBSpool commands to operate on
spool files based on their device class. The first part of this chapter addresses background jobs. The
“SPOOLER” section discusses the second form of background processing —
SPOOLCMD
files.
Note. It is recommended that this feature be used within a job, as it can tie up a terminal
indefinitely.
