   Sorry, I didn't get the original basenote, but there's a slight
   problem with FCHI on the 1000.  It won't do numbers between 0.0 and .5:
   The software maintenance request has been filed and the module is
   fixed (I believe in the 5.1 release), and besides; out of the billions
   and billions of numbers, who's gonna notice when a few of them don't
   work? 

   Well, I did.  Not having time to wait for the fix, I wrote a version
   of FCHI (1000 Macro) that the poster of the base note (steve@wayback.
   unm.edu -- but I don't know his path) is welcome to; please email a
   request to me and I'll send you a copy.
