  Can you provide more information on what you are trying to do? CMP blocks don't have descriptions. If you want to compare values in a calc block you just use basic math functionality. If you want to comment or document in a Calc block (notes, etc) then you just preface with a rem statement.

  IF (logical-expression-1)
  THEN
  OUT 1 = 1
  ELSE

  THEN
  OUT 1 = 2
  ELSE
  IF (logical-expression-3)
  THEN
  OUT 1 = 3
  ELSE IF (.....) THEN
