You can define a symbol to invoke RDBPRE. Once you are in the
    RDBPRE environment, you can specify the programming language and
    the input file specification. For example:

    $ RDBPRE :== $RDBPRE
    $ RDBPRE
    INPUT FILE> MYPROG.RFO/FORTRAN

    A more convenient method is to define a symbol that invokes a
    particular preprocessor. For example, if you frequently use
    the preprocessor with FORTRAN data manipulation language (DML)
    programs:

    $ RFOR :== $RDBPRE/FORTRAN
    $ RFOR MYPROGRAM.RFO

1    /BASIC

    Specifies that the input file is a BASIC source file. Following
    successful RDBPRE preprocessing, the resulting file is submitted
    automatically to the BASIC compiler.

2    /COBOL

    Specifies that the input file is a COBOL source file. Following
    successful RDBPRE preprocessing, the resulting file is submitted
    automatically to the COBOL compiler.

3    /FORTRAN

    Specifies that the input file is a FORTRAN source file. Following
    successful RDBPRE preprocessing, the resulting file is submitted
    automatically to the FORTRAN compiler.

4    /INITIALIZE_HANDLES

    The /[NO]INITIALIZE_HANDLES qualifier allow you to control
    whether RDBPRE will initialize RDBPRE-supplied database,
    transaction, and request handles. Use of the /NOINITIALIZE_
    HANDLES qualifier allows you to link a main image against a
    shareable image and share handles between the two.

           Format:
                  /INITIALIZE_HANDLES     (Default)
                  /NOINITIALIZE_HANDLES

    These qualifiers have no effect on whether or when handles are
    cleared in the generated code; they only control initialization
    of handles in declarations. Furthermore, they only affect
    database, transaction and request handles that RDBPRE declares.
    User-specified transaction and request handles will not be
    initialized when you use the /INITIALIZE_HANDLES qualifier.

    In RDBPRE when you use the /NOINITIALIZE_HANDLES qualifier,
    any handle you specify in your application program must also
    be specified in the shareable image.
