Discard.sound

The discard.sound command unloads a sound resource from the memory heap.

Syntax

discard.sound(byt A);

Remarks

In the PC version of AGI, this command points to a null function, and does nothing.

Early versions of AGI did not include a command to unload sound resources. Since sounds were usually small and only used in limited circumstances, this was not usually a problem. Beginning with version 2.938, Sierra added this command to allow sounds to be unloaded once they were no longer needed. However, they did not make the command functional in the PC version; it only unloads sounds in non-PC interpreters.

Possible Errors

Presumably, attempting to discard a sound that hasn't been loaded will cause errors and crash AGI.

Example

Code:

discard.sound(12);  [ does nothing on PC based system
                    [ on non-PC system, sound #12 is unloaded

Technical Information
