If you don't know the PostScript output filename (i.e., you
didn't set it to something in your code or you don't have a
variable that contains the name), then the chances
approach about 100% that its name is "idl.ps". It will
be located in the current directory:
CD, Current=thisDirectory
Print, thisDirectory

Here's one way:
SET_PLOT,'ps'
*do some plotting here*
psfilename= (FSTAT(!d.unit)).name
Note that the !d.unit variable seems to be 0 immediately
after the set_plot, but is set to the correct value after
there's been some graphics output. Bug or feature?
