Illustration of if- else statement:
IF OK-BALANCE NEXT SENTENCE ELSE MOVE 2 BALANCE-CODE
In this illustration, the OK-BALANCE is a condition name. No action is specific if this condition is true. And when the condition is false, BALANCE-CODE must be set to 2. The sentence is equal to the following flow chart.
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.
