Is it possible to use VERY LARGE const char (or int) arrays (much larger than the RAM size) WITHOUT uploading them to RAM? How must I define them?

Where do you expect the array to be stored then? Define VERY LARGE.

I expect it to be stored in the flash memory. It will be about 4..6 K bytes.

So why are you not storing them there? Have you looked at progmem tutorial in the tutorial forum?
