[comp.lang.postscript] Need error handler routines/examples

mhrabi@attcan.UUCP (Merv Hrabi) (08/23/90)

I need examples of error handling routines that will print
the command being executed and the operands on the stack.
Our postscript printer runs in batch mode so I need a routine
that will print an error page on the postscript printer.
If anyone has tutorial on postscript error handling routines,
I would appreciate receiving a copy.

        Thanks
