 5 and 37, it is followed by the most recently processed identifier, number
           and  symbol.   Only  the first eight characters of each name are
           displayed.

           the wrong value, the number of the right  hand  part  regression
           term  which  causes the error is displayed when the error number
           lies between 50 and 53.                                         
70 and 76, it is followed by the check value and the wrong value.   Instead
           of the wrong value, the value of the controlling variable of the
           next enclosing repetition  loop  is  displayed  when  the  error
           number is 76.
