    The AT&T SDS 4.1.6 Software Development Package generates
    COFF output files.   The AT&T SCDE 5.0/3 Package generates
    ELF output files, and can accept COFF .o files as input,
    with conversion performed internally.  AT&T SVR3.2.2 and above
    systems can execute ELF format executables.   SCDE 5.0/3 is
    available for SVR3.2 and may be installed in a 'transitional' 
    mode which allows both compiler environments on a machine at the
    same time.  In addition, SCDE 5.0 allows a choice of three modes:
    K&R, ANSI, and a mode which allows ANSI syntax and preserves K&R
    semantics in the areas where the semantics would be different
    (mostly involving promotion and unsigned comparison).
