This cross-posting originated by Vowels (and lifted in your reply to my to
reply to Gary Scott who thinks he is bits limited compared to what PL/I has
available in syntax and thus cant solve a complex bits problem.

So show us a PL/I bits solution for your "challenge" above or else I am
ignoring it since neither PL/I or Fortran can express a REAL with a million
bits precision using available REAL data types

Vowels says PL/I can declare string lengths > 32767 chars, as a PL/I
expert, what do you say?
