Thanks PCM, i read it, but i want to re-assemble it with PCWHD assembler not MPASM, as you said after importing hex and cof file in mpasm file is not ready to edit and assemble. is there any way to get asm file first and than assemble it with CCS assembler?

I don't think there is a way to prevent the compiler from inserting the
start-up code. If there was a way, I think it would be in the description
for the #build directive, such as 'no_startup' or 'no_init'. But I don't see
an option like that in the manual, so I don't think CCS has that feature.
