About a week ago I posted a request about how to make IslandDraw 2.1 read postscript
files generated by Mathematica 1.2 . I got inumerous replies, basically all
suggesting I use psfix to fix the postscript file. This is what I had done but
didn't make clear in my previous posting. The postscript file I want IslandDraw
to read  is self-contained (it prints and ghostscript can read it). IslandDraw is
not a full fledged postscript interpreter but it can read "good" postscript files.
Unfortunately it seems the Mathematica-generated postscript file is very complex
(specially the MathScale thing). Thus, short of stripping off almost everything
in the file, is there anything I can do to modify the postscript file to something
more conforming (and readable by IslandDraw) ?

I did tried the program "distill" but it failed as well.
The only thing that worked was to run Mathematica in a Tektronix 4014 window
and then dump the graphics to a file, use ps4014 (which is part of the Transcript
package) to convert it to a postscript file, which can then be read by IslandDraw.

Thus if anyone has any suggestions (like how to modify the postscript prologue as
it is done by LaTex people to get MacIntosh-generated postscript files to work with 
LaTex/psfig) I'd like to hear. 

Also, if someone has Mathematica 2.0, I would appreciate getting a sample
(psfixed) postscript file (of say, a sine function) so I can see if IslandDraw
can read it. If the postscript prologue hasn't been modified since version 1.2
of Mathematica, then there is no point in sending me such a file.

I was going to use Maple V, but it can't even calculate the numerical values
of my function (a confluent hypergeometric function like M(1,3/2,z) ).

Thanks.
