CHAPTER 2
Running NBSpool
This chapter provides information on running NBSpool. NBSpool is a command driven program.
When you run NBSpool, it gives you a
O>
prompt and waits for a command from you. Your
commands instruct NBSpool to display, modify, and delete spool files. NBSpool enables you to save
spool files in an organized manner, to print sections or all of a spool file and to merge spool files.
If NBSpool is run from a job, it behaves somewhat differently. First, no confirming questions are
asked. Also, if a command does not execute successfully, NBSpool terminates in an error state. The
program also recognizes the
INFO
parameter. If NBSpool is run with an
INFO
string, it executes the
command or commands that are passed in the string.
NBSpool operates in one of two modes, input mode and output mode. The mode determines the set
of valid commands and the type of spool file on which operations are performed using those
commands. The output and input commands are described in chapters 3 and 4.
The command mode can be changed at any time. The command prompt changes to reflect the
mode. When NBSpool is in output mode, the prompt is
O>;
in input mode, the prompt is
I>
