What's the point of it? I'm trying to do some minor JS programming, but the dummy-variable concept is mysterious to me.

It is a statement that always evaluates as TRUE, ensuring that the while() statement loops around again.

It is placed at the very end of the midirecv() ? code block, to avoid the accidental problem caused when the last statement does not always evaluates to TRUE, which would cause the while() loop to stop.
