As a point of interest, the PostScript syntax is directly related to a 
general machine independent programming language called Forth.  Forth 
was used to control telescopes in the days of the minicomputer.  It 
migrated to various microprocessors and was used a lot in process 
control applications.  Forth is still alive and well today.
