ASM code modified and configured

Hi
I have some sample ASM code from a Microchip Application Note, currentyl data is parsed from one element of the chip to the Micro controller over the SPI bus. I need the code modifying so that this data that is on the SPI bus is made available on an external pin. I also need access to modify the setup and control registers. We use Flowcode so would need the new code to compile through Flowcode as a inserted asm module.
