Tracing the lp, lpstat, or cancel commands

To trace the lp, lpstat, or cancel command:

1. Set the AOPTRACEON variable:

   export AOPTRACEON=1

   _______________________________________________________

2. Enter the lp command:

   lp ...

   Tip: To set AOPTRACEON only for one command, set the variable on the same line as the command:

   AOPTRACEON=1 lp ...

   _______________________________________________________

To stop tracing the lp, lpstat, or cancel command:

1. Unset the AOPTRACEON variable. You need to unset AOPTRACEON only if it is set in the z/OS UNIX shell. The variable is set in the shell if you used the export command to set it.

   unset AOPTRACEON

   _______________________________________________________

2. Reenter the command:

   lp ...
