VERSION          Set TASM assembly mode                             Directive

  In code:
  VERSION version_ID

  Command-line option:
  /uversion_ID

    The VERSION directive (introduced in TASM v3.0) lets you specify which
    version of Turbo Assembler or MASM you're writing particular modules
    for. This is helpful for upward and downward compatibility of various
    versions of TASM and MASM. The VERSION directive places Turbo
    Assembler into the operating mode for the specified version.


    You can specify the following legal version IDs:

             M400        MASM 4.0
             M500        MASM 5.0
             M510        MASM 5.1
             M520        MASM 5.2 (Quick ASM)
             T100        Turbo Assembler 1.0
             T101        Turbo Assembler 1.01
             T200        Turbo Assembler 2.0
             T250        Turbo Assembler 2.5
             T300        Turbo Assembler 3.0
             T310        Turbo Assembler 3.1
             T320        Turbo Assembler 3.2
             T400        Turbo Assembler 4.0

    As an example, if you wanted to assemble a program written for MASM
    5.1, you could leave the source for the program intact and use the
    switch /uM510.


    Note:       1. The VERSION directive always selects MASM mode by
                   default, because that is the starting mode of operation
                   for both MASM and Turbo Assembler.
                2. The VERSION directive limits the high-priority keywords
                   available to those in the specified compiler and version.
                   As a result, some features that were added to later
                   versions are unavailable to you.
                3. From Ideal mode, the VERSION directive is unavailable
                   if you select a version prior to T300. To use the
                   VERSION directive in this case, you must switch to MASM
                   mode first.
                4. No attempt is made to limit access to low priority key-
                   words since these will not affect compatibility.


    Previous versions of Turbo Assembler controlled MASM compatibility
    with directives such as MASM51, NOMASM51, QUIRKS. The VERSION
    directive supersedes these older directives. Refer to the complete
    list of keywords available with each prior version of Turbo Assembler.
