    /tset/XOPEN.os/charhandle/Misascii/T.isascii 1 Failed
    Test Information:
    isascii(0x80) failed
    isascii returns non-zero for ASCII characters
    Current language is VSX4L1
    Current category is LC_ALL
    Expected return value: 0
    Actual return value: 1
    isascii(0x81) failed
    isascii returns non-zero for ASCII characters
    Current language is VSX4L1
    Current category is LC_ALL
    Expected return value: 0
    Actual return value: 1
    .

    In order to achieve portability of applications the functions isacsii()
    and toascii() are implemented to deal with valid EBCDIC characters in the
    range of 0 to 255.

    Truncation to 7 bits results in invalid EBCDIC characters.

    This is documented in the manual.

    This is also true for the following tests::

    ANSI.os/charhandle/isascii Test No: 1
    ANSI.os/charhandle/Mtoascii Test No: 1
    ANSI.os/charhandle/toascii Test No: 1

    Review Type TSMA Review

    Status Complete
    Review Recommendation No Resolution Given
    Review Response
    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.

    Review Type SA Review
