Section 9,1,2: Severe_Messages

 Must be corrected before the program can be compiled.  An object

 The severe messages follow (in alphabetical order):

  o  MESSAGE:  Implied DO loop increment is 0

     EXPLANATION:  The value of the implied DO loop increment was
     zero.

  o  MESSAGE:  This DATA implied-DO list name must be subscripted

     EXPLANATION:  In a DATA statement, an implied DO loop referred
     to a variable missing a subscript.  For example:

        INTEGER A(10)
        DATA (A,I=3,5) /3*20/

     The correct use for this example is DATA (A(I),I=3,5) /3*20/.
