BEEPING

Syntax BEEPING
Location QL ROM

This is a simple function which returns either 1 (true) if any sound output from BEEP is still running or 0 (false) if not.

Example

BEEPING is rather useless in a formulation like: IF BEEPING THEN BEEP

because this is less efficient than BEEP on its own which has the same effect. However, where you want to ensure that your program generates the chosen sound, because of the QL’s multi-tasking abilities, it may be useful to use this function in case another program is executing a BEEP command when you want to - you could then either wait or simply override that sound by using BEEP followed by your own sound generating BEEP command. For example:

10 REPeat check_beep: IF NOT BEEPING THEN EXIT check_beep
20 BEEP 100,20

NOTE

This function did not work correctly on Minerva before v1.98.

CROSS-REFERENCE

BEEP activates the speaker.
