Minor bug in CHOOSE (rev. 6975) - Snorre - 01-16-2015 02:35 PM
Hello,
The following crashes the Prime:
Code:
KEY K_Menu()
BEGIN
CHOOSE(N,"Lunch",{"Salad","Yogurt"});
RETURN "Steak";
END;- Press user key [Menu]
- Press user key [Menu] again
- Cancel selection by tapping outside of choose box

And crashes the emulator, too!

Pressing user key [Menu] a third time followed by another key results in
- either an immediate crash/reboot (e.g. on [Esc] or [Enter])
- or an endless flickering exclamation mark symbol ([On]+[Symb]-restart needed) (e.g. on [SIN] or [5])

Guessing the user "choose" is doing something funny and assuming there will never be more then a single choose up at once. I can't see any possible way of actually getting a second one up at a time without going through the user key mechanism though.

Hello Tim,
Therefore I'd call it a minor bug (maybe more an inconvenience) and had never even noticed if I hadn't accidently hit the user key twice and got curious about the second choose box popping up.
I tried the same with an input form, but that rejected to open another one while the first was still open. Also, [View] and [Paste] won't show up while another choose box is waiting. Maybe there's a check that could easily be adapted to user choose boxes too; something similiar to the PPL workaround
Code:
choosing:=0;
EXPORT MYCHOOSE(selection,title,options)
BEGIN
IF choosing THEN RETURN 0; END;
choosing:=1;
CHOOSE(selection,title,options);
choosing:=0;
RETURN selection;
END;Greetings
