A Tale of Three Beeps

Are your programs not executing instructions in VB4 that were executing in VB3? Try this in Qbasic, VB3, and VB4:

 
BEEP: BEEP: BEEP



If you F8-step through this very complex code, you will hear three beeps except when running on VB4, which will produce only two beeps. Reserved words, such as Beep, and Cls are treated as labels. Notice the colon.

Using VB4:

 
BEEP
BEEP
BEEP





will give the expected three beeps.
