    echo.Description:
    echo.        'abc10def3' is bigger than 'abc9def4' because
    echo.        first number in first string is 10
    echo.        first number in second string is 9
    echo.        whereas normal text compare returns 
    echo.        'abc10def3' smaller than 'abc9def4'
    echo.
    echo.Example:
