     NAME
          as - common assembler

     SYNOPSIS
          as [-m] [-n] [-o objfile] [-R] [-V] filename

     DESCRIPTION
          The as command assembles filename.  The following flags may
          be specified in any order.

          -o objfile   Put the output of assembly in objfile.  By de-
                       fault, the output filename is formed by remov-
                       ing the .s suffix, if there is one, from the
                       input filename and appending a .o suffix.

          -n           Turn off long/short address optimization.  By
                       default, address optimization takes place.

          -m           Run the m4 macro pre-processor on the input to
                       the assembler.

          -R           Remove (unlink) the input file after assembly
                       is completed.  This flag option is off by de-
                       fault.

          -V           Write the version number of the assembler being
                       run on the standard error output.

     WARNINGS
          If the -m flag option is used, keywords for m4 cannot be
          used as symbols (variables, functions, labels) in the input
          file because m4 cannot determine which are assembler symbols
          and which are real m4 macros (see m4(1)).
     BUGS
          Arithmetic expressions are permitted to have only one for-
          ward referenced symbol per expression.
