Is there any way in which a program can find out the filename of the
currently open postscript file. I know you can do help,/device to
display it on the screen, but I'm not sure how to put the filename into
a variable.
Cheers,
Tim

The default filename is "idl.ps". If you set your own filename with the
DEVICE,FILENAME=... command (after doing SET_PLOT,'PS'), then the easiest
way to know the filename is to keep track of the one you used!
If you simply have to do it automatically, then do:
J=FSTAT(!D.UNIT) &FNAME=J.NAME
(This will only work if something has already been written out to the file.)
I imagine that you might be wanting to do this to find out the directory
in which the file has been created. I think the only way to do this is
to include a full path spec in DEVICE,FILENAME=...
