9 Output Operations
BEEP can signal that a particular computation or program segment is complete. It can also be used to audibly indicate that the computer is ready for input, so that the operator does not have to remain at the keyboard.
Here is an example:
250 FOR I=1 TO 25 260 BEEP 270 INPUT "ENTER VALUE:";Value(I) 280 NEXT IIn this case, a beep signals the operator when the program is ready for input. Another practical use for BEEP is to signal the operator when a data-entry error occurs.
As another example, here is a musical sequence to signal the end of a program:
10 FOR Beep=1 TO 7 20 READ Delay 30 WAIT Delay*10 40 BEEP 50 NEXT Beep 60 DATA 80,40,15,15,40,80,40 70 END
