When I run this code in the Windows IDE (Feb 2018, 6M62) and press a key, the IDE makes a “ding” noise. Or maybe my machine does. I don’t know why. Will interpreters do that, too? Because I was thinking of playing my own sound effect at one point (right after a “wait for any key”), and when I test it, the “ding” ends up playing along with my sound, and I don’t want it to.

Lab is a room.
When play begins:
wait for any key;
say "Hello.";
(Edited to clarify what I meant.)
