     DESCRIPTION
          Increments the value stored in the variable  whose  name  is
          varName.   The value of the variable must be an integer.  If
          increment is supplied then  its  value  (which  must  be  an
          integer)   is  added  to  the  value  of  variable  varName;
          otherwise 1 is added to varName.  The new value is stored as
          a  decimal  string  in variable varName and also returned as
          result.
