How do i keep PBP (picbasic pro) compiled code out of 0000h - 0003h ? When I try to load a .hex file with romzap that i've done in PBP, it says the code is using that area and will overwrite the boot loader. I've tried using DEFINE ONINT_USED 1 but that doesn't seem to help. I'd like to keep Interrupt function if possible.
