                     Fortran Carriage Control with f77

     Normally no special processing of carriage control characters  is
     done  by the f77 I/O library.  There are two ways to get carriage
     control  character  processing:  open  the   output   file   with
     "form=print":

             open( unit=6, form='print' )

     or use the fpr filter on the output:

             a.out | fpr

     Both of these will single space for a blank in column one, double
     space for a '0' in column one, and replace a '1' in column one by
     a form feed to skip to a new page.

     With "form=print", any other character appearing in  column  one,
     including '+', is deleted with no effect on vertical spacing.

     With fpr, the effects of '+' (overprinting) are  simulated  using
     backspaces.   Characters in column one that are not recognized as
     carriage control characters are printed in column one.  If  there
     were  any invalid carriage control characters, before ending, fpr
     writes out how many invalid  carriage  control  characters  there
     were.
