OpenVMS usage: cond_value
    type:          longword (unsigned)
    access:        write only
    mechanism:     by value

    Longword condition value. If an odd numeric value is returned,
    the next call to the built-in procedure FILE_SEARCH automatically
    sets the TPU$M_REPARSE bit in the flags longword. TPU$M_REPARSE
    is also set if the result-string has a length of 0.
