MORE INFORMATION
================

The following program demonstrates the problem:

Sample Code
-----------

  C Compile options needed: -Ox -G5

     20  WT     = WT*(0.5/(I+1))
         TERM   = WT*(.805)
         SUM    = SUM + TERM
         I      = I + 1
         ADJ    = ADJ*4.3/(2.0*I)
         IF (TERM.GE.(0.1*SUM)) GO TO 20
         END
