ON TIMER does not trigger while waiting for INPUT$()

[Elvagor]

As per the subject. Just wondering if this is expected/wanted.
Thanks!

I just checked with this test code:

10 ON TIMER(1) GOSUB 1000
15 TIMER ON
20 A$=INPUT$(1): GOTO 20
1000 PRINT TIMER: RETURN

Both GW-BASIC and PC-BASIC show the same behavior: the timer routine is not executed while waiting for input but instead is run once every time a key is hit. This makes sense, as the interpreter can't execute event loops while being stuck in a given function (in this case, INPUT$).

So yes, it's expected behaviour.
