Chloé,

PSON and PSOFF are meant to be drop in replacements for the SET_PLOT
commands used to select and deselect the PostScript device. They
include additional intelligence which makes configuring the PostScript
device much easier than using DEVICE commands. If I was you, I'd
modify your code to use it.

PSON does not impose limitations on the DEVICE commands you can use
after PostScript output has been selected. For example, if you want to
select a Times Roman font

pson
device, set_font='Times Bold', /tt_font ; select a TrueType font
plot, x, y, title='My Test Plot', font=1 ; tell PLOT to use the
TrueType font
psoff

See pages 372 and 373 of my book for more information.

Cheers,
Liam.
