Shell Version -21328Failed invoking <symbol>

I can confirm that this PRG causes an out of memory error in the simulator, but I'll need more information to provide you with any useful suggestions. Can you provide some of the code for the app, or describe what the app is doing? Are you loading any resources (bitmaps, fonts, etc.) with this app?

Thanks. Source code is available here: https://github.com/PerArneng/bigheart

No bitmaps loaded. Just a simple field. It has worked in the simulator before.

Every line of code you write costs memory in CIQ, even if you don't execute it.
So even before you start your app you've only got a couple of thousand bytes left.

Your font takes up more than 3000 bytes. That's because
a) dictionaries are not memory efficient
b) every array you use (I think you have 78) takes 24 bytes + 1 extra byte for each value it holds (+4 bytes for each Number value)

If you put a "System.println(System.getSystemStats().usedMemory);" before and after the initialization of your font and remove the first 4 entries (so you don't run out of memory), you can see it for yourself.

I think the easiest solution for your problem is to flatten the structure of your font, so that each char only has 1 array. This would mean some minor changes in your draw function, but using modulo that shouldn't be too difficult to do.

Thanks . Ok i see. But people can use images and other resources. Are we talking about stack vs heap here?

Everything in MonkeyC is handle/body, so for the most part we're talking about heap.

More out of memory problems

I got another Out Of Memory error and i have really been trying to minimise allocations. I have just a few allocations but i still cant get the simulator to work.
I got the code to work with the previous project i hade but with this new one i have no look. Is there a way to profile my app so that i can resolve these issues
myself?
