    Problem Text
    On a system using EBCDIC-code it is possible to implement isascii and
    toascii so that the tests of the VSX-suite run successfully. But as a
    result of such an implementation programs using isascii and toascii in
    a UNIX-like manner will not run correctly. E.g. they expect that
    isascii((int)'C') != 0. If we choose the following implementation on
    an EBCDIC-system:

    isascii(c) ((unsigned(c) <= 0xFF)
    toascii(c) ((c) & 0xFF)

    the program will usually run correctly. But some VSX-tests will fail
    with this implementation. Therefore we suggest that these tests should
    not be used in an EBCDIC-environment. They require an implementation that
    is a hindrance of portability and therefore against the interests of
    the user.

    The same aplies for the following Tests:

    XOPEN.os/charhandle/Mtoascii/T.toascii
    XOPEN.os/charhandle/isascii/T.isascii
    XOPEN.os/charhandle/toascii/T.toascii
    Test Output
    /tset/XOPEN.os/charhandle/Misascii/T.isascii Failed

    Review Response
    This issue has been dealt with in MSF4.016 which included the following
    commentary:

    -----------
    This request raises the issue as to the meaning and usefulness of the isascii()
    and toascii() functions in an environment which suports the EBCDIC character
    set. It is unclear that the facilities provided by isascii() and toascii()
    can be used in a sensible manner in this environment and while it is
    accepted that the system under test does not match the specification , it
    should not affect applications that are being ported to this environment.

    It is recommended that this is treated as a minor system fault.
    -----------

    The test suite matches the specification and it is not recommended that this
    request should be granted as a test suite deficiency.
