Write a smaller program, or use a larger PIC......
This is bit like asking 'my petrol tank holds 20 gallons, how can I put thirty gallons into it without any overflowing'...
However a study of the existing code, may show areas where space can be saved, also increasing the optimisation level, may help a little.

If a newbie says he's using the 18F458 and he's out of ROM,
he is almost certainly using the demo.

I forget, we are getting hit with a lot of student cries for help.
