 To Jan Stout
 JS>So I think you unwillingly (?) created another FOR NEXTer.
 What a pleasure to hear that!  In return I'll ease off of my position  about
the decimal point indicating double precision.  (I may not change  my own
Forth in the immediate future, but at least I see what you mean  a little
better.)
 JS> : THRU ( 1st last)
 JS>   1+ OVER -
 JS>   FOR  DUP PUSH  LOAD  POP 1+  ?SCROLL  NEXT  DROP ;
  Thank you very much for the above.  How stupid of me not to have seen  it. 
At least learning and thinking are benefits from  arguments/discussions about
what should be in a Forth standard!
  (To anyone listening who doesn't follow all of the above, THRU in  cmFORTH
kept the index on the stack, and thus could not be used to load  a range of
screens that passed data on the stack across screen  boundaries.  I "solved"
it in Pygmy with a sledge hammer and wished for  an upcounting FOR NEXT index
to make it prettier.  Jan has showed me  how I should have done it.  By the
way the ?SCROLL is only used in the  debugging THRU (it allows a keypress to
temporarily halt the display).  It is omitted from the regular THRU.)
  And, furthermore, I am amazed and delighted that we are able to  converse
across such a distance: from central Texas to the Netherlands!   I understand
the Netherlands has a long history of free thinking and  tolerance of ideas.
