Many thanks! That is great news, my search of this group had turned up
only mention of LaTeX package psfrag in 1997...

I'll try this at work in the morning, for use. Is the setting of font
to 0 one of the critical tricks?

OK, understood.

Excellent! So the below could be put into a separate .tex file and
\input into the main document as I am used to doing under Matlab with
the laprint program.

Understood.

Yes, OK.

Ah, this part is new to me. Any idea what this is repairing, since
you've already specified emcapsulated PS in your IDL program. (I
understand the perl part after that to remove the preview TIFF image.)

Fantastic! I'll let you know how this goes.
