Tim said that access to Mercury will not be

done until Wednesday.

An easier way to use Mathematica on Vincent is to create a file.  

I usually call the File 

             abc.math 

or or something ending in .math.


Then I type 

math            (* to start the Mathematica program *)

                (* and inside Mathematica I type *)

Get["abc.math"]   (* this calls the program into Mathematica *)

                   (* To print out a picture or a graph *)

Display["abc.ps",Out[5]]    (* Will write the material on line 5 to
                               a file called abc.ps.

Quit               (* leaves Mathematica *);


In Vincent now;

add math                      (* gets the program that you want to run.  *)

psfix abc.ps > abcfix.ps      (* makes the abc.ps printable and puts
                                 it into the file abcfix.ps *)

lpr abcfix.ps       (* or what ever the common printer command for you is *)
