idas(M)                       06 January 1993                        idas(M)


 Name

    idas - assembler used by the Link Kit

 Syntax

    idas [-dl] [-m] [-n] [-o objfile] [-R] [-V] [-Y  [md],dir] filename

 Description

    The idas command assembles the named file.  The following flags may be
    specified in any order:

    -dl Do not produce line number information in the object file.

    -m  Run the m4(CP) macro processor on the input to the assembler.

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

    -o objfile
        Put the output of the assembly in objfile.  By default, the output
        file name is formed by removing the .s suffix, if there is one, from
        the input file name and appending a .o suffix.

    -R  Remove (unlink) the input file after assembly is completed.

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

    -Y  [md],dir
        Find the m4 preprocessor (m) and/or the file of predefined macros (d)
        in directory dir instead of in the customary place.  There must be a
        space between the -Y flag and its options.

 Warning

    If the -m (m4 macro processor invocation) option is used, keywords for m4
    cannot be used as symbols (variables, functions, labels) in the input
    file since m4 cannot determine which are assembler symbols and which are
    real m4 macros.

 Limitations

    idas is intended for use by the Link Kit. The as(CP) assembler should be
    used if an assembler is needed for program development. as is supplied as
    part of the SCO UNIX Development System, which also includes the C com-
    piler cc(CP), the link editor ld(CP), object libraries, and header files.

    The .align assembler directive may not work in the .text section when
    optimization is performed.

    Arithmetic expressions may only have one forward referenced symbol per
    expression.

    Wherever possible, the assembler should be accessed through a compilation
    system interface program such as cc(CP) or rcc(CP).

 Files


    /bin/idas   idas executable file
    TMPDIR/*    temporary files.  TMPDIR is usually /usr/tmp but can be rede-
                fined by setting the environment variable TMPDIR (see temp-
                nam() in tmpnam(S)).
