  23. <Ahem> David's is correct; yours is wrong: you translate (possible)
  24. non-alphabetic characters among XRANGE('A','Z') to different, not
  25. necessarily non-alphabetic, characters among XRANGE('a','z').  The Rexx
  26. standard does not guarantee that XRANGE('A','Z') contains only alphabetic
  27. characters; nor even that it contains the same number of characters as
  28. XRANGE('a','z'); nor that the two don't overlap.  I regularly use a
  29. dialect of Rexx for which not all these assumptions are true.
