I don't know. I don't use Annotate and when I try to execute
the code you have here Annotate crashes with a CASE STATEMENT FOUND
NO MATCHES error. (Sigh...)
But my reading of the documentation (no guarantees) would
suggest that you don't need that last Set_Plot, 'PS'
command. I think what this is doing is causing the file
that you actually created (and Annotate wrote into, presumably)
to be overwritten. You might try giving your PostScript files
unique names with the Filename keyword so this doesn't surprise
you like this. :-)
Cheers,
David
