Hello, Peter:
Thank you for your reply.
Hello, Reynard:
Thank you very much for your point. I have solved the problem by disable the indexed addressing mode. I am quite new to PIC18. Thank you very much for all your help. But just to clarify one point. The '\0' is not necessary to be in my program. I think the sourceboost is taking care of it.
Thanks all~.
Regards,
Acroty
