ert0056   Read of random library table failed

    Solution:  Try running the DOS CHKDSK /F utility to see if your
    disk is corrupted.  If the disk is not corrupted, try regenerating or
    re-installing the library in question.  To determine which library
    caused the problem, link with the VERBOSE option.  If the problem
    persists, link with the NOEXTDICTIONARY option in order to ignore the
    extended dictionary.
