COBOL fingers
     
        /koh'bol fing'grz/ Reported from Sweden, a (hypothetical)
        disease one might get from coding in {COBOL}.  The language
        requires code verbose beyond all reason (see {candygrammar});
        thus it is alleged that programming too much in COBOL causes
        one's fingers to wear down to stubs by the endless typing.
