    Problem Text
    The tests in the string test area assume that the host system is
    ASCII-based but there is nothing in ANSI or POSIX that requires this
    to be so. Several test programs use the fact that in ASCII, turning
    on the high-order bit of a byte containing a printable character
    changes the value of the byte. This is not always true for EBCDIC
    charcters - the value may stay the same [('a' | 0xf0) == 'a' in
    EBCDIC]. Tests that assume the state of any bit (including the
    high-order bit) of any character are not valid. The following tests
    are failing because they assume they can turn on the high-order bit to
    change the value of a printable character:

    ANSI.os/string/Mstrchr/T.strchr 2,
    ANSI.os/string/Mstrcmp/T.strcmp 1,
    ANSI.os/string/Mstrcmp/T.strcmp 3,
    ANSI.os/string/Mstrrchr/T.strrchr 2,
    ANSI.os/string/strchr/T.strchr 2,
    ANSI.os/string/strcmp/T.strcmp 1,
    ANSI.os/string/strcmp/T.strcmp 3,
    ANSI.os/string/strcspn/T.strcspn 1,
    ANSI.os/string/strncmp/T.strncmp 1,
    ANSI.os/string/strncmp/T.strncmp 3,
    ANSI.os/string/strpbrk/T.strpbrk 2,
    ANSI.os/string/strrchr/T.strrchr 2,
    ANSI.os/string/strspn/T.strspn 1,
    ANSI.os/string/strstr/T.strstr 2,
    ANSI.os/string/strtok/T.strtok 1, and
    ANSI.os/string/strtok/T.strtok 2.

    Note: this request was originally submited with our number of vsx.007.
    It was refused because it listed a non-existent test. The request
    incorrectly identified strspn 2 as one of the tests in error but this
    should have been strstr 2. In addition, one of the tests originally
    referenced by vsx.008 should have been reported here. Both tests are
    correctly identified in this request which replaces vsx.007. Another
    request will take the place of vsx.008.
    Test Output
    /tset/ANSI.os/string/strchr/T.strchr 2 Failed
    Test Description:
    strchr() returns a null pointer if character c does not occur in
    string s.
    Test Strategy:
    VERIFY NULL return when character is not in the string.
    Test Information:
    strchr did not return expected value
    pointer & value of first argument : 0x37320f0
