 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 - is specified
      or if no file names are given.  The first character of each line is
      assumed to be a control character.  The following control characters
      are interpreted as indicated:

	   (blank) Output a single new-line character before printing.

	   (space) (XPG4 only.)	 The rest of the line will be output without
		   change.

	   0	   Output two new-line characters before printing.

	   0	   (XPG4 only.)	 A <newline> shall be output, then the rest
		   of the input line.

	   1	   Output a new-page character before printing.

	   +	   Overprint previous line.

	   +	   (XPG4 only.) The <newline> of the previous line shall be
		   replaced with one or more implementaions-defined
		   characters that causes printing to return to column
		   position 1, followed by the rest of the input line. If
		   the + is the first character in the input, it shall have
		   the same effect as <space>.

      Lines beginning with other than the above characters are treated the
      same as lines beginning with a blank.  The first character of a line
      is not printed.  If any such lines appear, an appropriate diagnostic
      is sent to standard error.  This program forces the first line of each
      input file to start on a new page.

      (XPG4 only.) The action of the asa utility is unspecified upon
      encountering any character other than those listed above as the first
      character in a line.

      To view the output of FORTRAN programs which use ASA carriage control
      characters and have them appear in normal form, asa can be used as a
      filter:

	   a.out | asa | lp

      The output, properly formatted and paginated, is then directed to the
      line printer.  FORTRAN output previously sent to a file can be viewed
      on a user terminal screen by using:

 EXTERNAL INFLUENCES
    Environment Variables
      LC_CTYPE determines the interpretation of text within file as single-
      and/or multi-byte characters.

      LC_MESSAGES determines the language in which messages are displayed.

      If LC_CTYPE or LC_MESSAGES is not specified in the environment or is
      set to the empty string, the value of LANG is used as a default for
      each unspecified or empty variable.  If LANG is not specified or is
      set to the empty string, a default of "C" (see lang(5)) is used
      instead of LANG.

      If any internationalization variable contains an invalid setting, asa
      behaves as if all internationalization variables are set to "C".	See
      environ(5).

    International Code Set Support
      Single- and multi-byte character code sets are supported.
