 Subj: Why is PostScript not Forth ?

  Doug -
   As I pointed out in the FIGGY BAR conference on 9 Feb 1990 on GEnie,
 PostScript may fairly be referred to as a subset or superset (depending
 on your perspective) of Forth, but it is NOT Forth. If PostScript 
 qualifies as Forth by your definition then all other PostFix, stack
 oriented languages such as REPTL, Fifth, and STOIC do so as well. This
 is clearly not the case. If an analogy may be drawn it might be this:
  All Cactii are succulents, but all succulents are not cactii. All
  Forth are postfix stack machines, but not all postfix stack machines
  are Forth. Sharing mechanisms is only part of the definition. PostScript
 is no more Forth than a golfcart is an automobile, though both are
 motor driven and most have four pneumatic tires and propel people and
 their luggage from point-to-point.
