Where's this unused memory? I'm not aware of memory going unused.

• Flash is full -- firmware plus library pages use everything available.
• Non-volatile RAM is full -- all 2kb of it.
• Volatile RAM is full -- we've had to fix stack overflow issues in this 4kb region.
• We've even used the semi-volatile 55 bytes of RAM in the LCD controller.

Paul;

I don't have time to re-read my 370 page hardbound 34s manual and all the associated posts here. I remember something though. Isn't there a chunk of memory that is designated by the hardware to be used for key assignments (but not data)? IIRC it can be filled with programs assigned to specific keys, however; those new functions need to be read in and not pushed in as programs from the keyboard. That's what I was referring to as not "easily accessible to us mortals".

The old brain was under the impression that some of this space was left unused, but I could have misunderstood since I didn't experiment with custom builds, or I could be remembering something from your development stage that is no longer true. That's the "unused memory" I was talking about.

I wore out my first 34s, but I didn't wear out each and every function. There's a lot of them.
