subroutine s9comp (nspace, fmt, nwd)
  c august 1979 edition. w. fullerton, c3, los alamos scientific lab.
  c
  c s9comp returns a format in array fmt suitable for writing a header
  c that contains the 6-character function names at the top of two columns
  c of function values.  the position of these names depends on nspace,
  c the number of spaces beyond the carriage control column to skip.
  c
  c the format returned in fmt is
  c          (nspace x, nwd a nch, 26x, 1hd, nwd a nch)
  c where  nwd = the number of integer words required to hold 6 characters
  c   and  nch = the number of characters in one integer word.
  c
  c s9comp also returns nwd, the number of integer words required to
  c hold 6 characters.
