Hi,

You can order 10F202 for prototyping, that is the same as 10F200 but has
twice as much program memory and a bit of more ram as well. When you
finished with the functionality, you can check the size of your code and ram
usage, and then you may try to optimize the code if necessary to fit into a
10F200.

You don't have to use FSR/INDF, but you can... However, I'd suggest not to
use numbers as ram addresses, but defining variables in 'cblock' or 'res'
instead.
