     NAME
          asa - interpret ASA carriage control characters

     SYNOPSIS
          asa [files]

     DESCRIPTION
          Asa interprets the output of FORTRAN programs that utilize
          ASA carriage control characters.  It processes either the
          files whose names are given as arguments or the standard
          input if no file names are supplied.  The first character of
          each line is assumed to be a control character; the meanings
          are:

          ' '     (blank) single new line before printing

          0       double new line before printing

          1       new page before printing

          +       overprint previous line.

          Lines beginning characters other than the ones above are
          treated as if they began with ' '.  The first character of
          the line is not printed and an appropriate diagnostic will
          appear on standard error.  This program forces the first
          line of each input file to start on a new page.

          To view correctly the output of FORTRAN programs which use
          ASA carriage control characters, asa could be used as a
          filter thus:

               a.out | asa | lp

          and the output, properly formatted and paginated, would be
          directed to the line printer.  FORTRAN output sent to a file
          could be viewed by:

               asa file
