    Problem Text
    The tests in the charhandle test area assume that the host system is
    ASCII-based but there is nothing in ANSI or POSIX that requires this
    to be so. The tests compare the result from functions such as
    isalnum() against an ASCII-based table called "asc_table" defined in
    SRC/INC/nlsclass.h. The table is not correct for host systems that
    are EBCDIC-based. The character 0x30 has no special meaning in
    EBCDIC. This problem causes 26 failures in the following test sets:
    ANSI.os/charhandle/Misalnum/T.isalnum 2,
    ANSI.os/charhandle/Misalpha/T.isalpha 2,
    ANSI.os/charhandle/Miscntrl/T.iscntrl 2,
    ANSI.os/charhandle/Misdigit/T.isdigit 1,
    ANSI.os/charhandle/Misgraph/T.isgraph 2,

    Test Output
    /tset/ANSI.os/charhandle/isalnum/T.isalnum 2 Failed
    Test Description:
    In the 'C' locale isalnum() classifies characters according to the
    ASCII 7-bit coded character set.
    Posix Ref: Component ISALNUM Assertion 8.1-04(A)

    Test Strategy:
    FOR C locale (default) :
    FOR all ASCII values :
    VERIFY value returned by isalnum() against expected value
    Test Information:
    isalnum(0x30) failed
    isalnum returns non-zero for alphanumeric characters
    No current language has been set
    Expected return value: 64
    Actual return value: 0
