2A(1)                                                       2A(1)

     NAME
          0a, 1a, 2a, 4a, 5a, 6a, 7a, 8a, 9a, ka, qa, va, xa -
          assemblers

     SYNOPSIS
          2a [ option ... ] [ name ... ]
          etc.

     DESCRIPTION
          These programs assemble the named files into object files
          for the corresponding architectures; see 2c(1) for the cor-
          respondence between an architecture and the character (0, 1,
          etc.) that specifies it.  The assemblers handle the most
          common C preprocessor directives and the associated
          command-line options -D and -I.  Other options are:

          -o obj
               Place output in file obj (allowed only if there is just
               one input file).  Default is to take the last element
               of the input path name, strip any trailing .s, and
               append .O, where O is first letter of the assembler's
               name.

     FILES
          The directory /sys/include is searched for include files
          after machine-dependent files in /$objtype/include.

     SOURCE
          /sys/src/cmd/2a, etc.

     SEE ALSO
          2c(1), 2l(1).
