It may be noted that any If sentence can be alternatively written by just negating the condition. In order to maintain the meaning of the unique sentence, the then and else parts are to be interchanged. Therefore the following sentence has similar meaning as the one illustrated above.

IF NOT OK-BALANCE MOVE 2 TO BALANCE-CODE ELSE NEXT-SENTENCE

If preferred, the ELSE NEXT SENTENCE phrase may be dropped to get the equivalent form as shown.

 IF NOT OK-BALANCE MOVE -2 TO BALANCE-CODE.
