Now I'm sure this is going to be embarrasingly obvious/simple, *but*

I'm using a 16F1824, the spec says the following...

"Up to 8 Kbytes Linear Program Memory"

however, when I compile my program & goes above 4096 (as shown in microcode studio) I get an error "ARGUMENT OUT OF RANGE" ....if I strip some code out, to take it below 4096...then all is well again.

So where has the extra 4k of programming space gone?!! ie how can I can take advantage of it?!
