Allocating registers from RAM for own use

Like Nigel says, the Pic16F range used to be. and still is, very popular , even though its a few years since I used the Pics, a bit surprised when you say that there is a Lot of the Pic18F24K20 out there ??
That said, in our latter days of Assembly coding the 18F range were our chips of choice.

For Maths and similar routines in Assembly code you will find lots here-

Hi!
Now I understand the memory map. I still have so many questions that there are symbolic names next to the titles at the beginning of the file register. What does that mean?
I chose this PIC because there is a lot of it out there.

If you keep the .pdf version of the datasheet open in your PC, Ctrl + F is your friend for any doubts like that.

Reading carefully the full datasheet in the long term, saves you a lot of time.

Ok. Thanks at answers.
