Question on starting location using PIC 18F4420

I have a simple question.

I am using a bootloader for the 18F4420 and am using the CCS C Compiler. What instruction do I place in code that will place my starting location of the Main Progran at 0200h in program memory? Is it the #org start,end ?? Is there a instruction where I just give it a starting location only? Purpose is because the bootloader occupies up to 01FFh.

thanks...garry.

check out the #build directive.

FYI I don't like low memory bootloaders. It forces you to have code that is bootloader aware and it costs additional cycles to process interrupts.
