  Transfers control to a statement based upon the value of an
  expression within the statement.  Statement format:

    GO TO (slist)[,]e

     slist  Is a list of one or more labels of executable
            statements separated by commas. The list of labels
            is called the transfer list.

     e      Is an integer arithmetic expression in the range
            1 to n (where "n" is the number of statement labels
            in the transfer list).

  If the value of e is less than one or greater than the number of
  labels in the transfer list, control is transferred to the first
  executable statement after the computed GO TO.
