Please note that I tried out some of the hints to former
similar requests to MUG. However they did not work.
I use i386 linux, kernel 2.4.10, KDE2.2.1, and maple7.

Dear Mug,
while I can easily create a ps file from a plot object in a
worksheet using the plotsetup command, this does not
seem to work from within a procedure.
Below there is an example for a procedure which fails
to create a postscript file. Can someone please advise?
Thank you very much,
Martin
