    Yeah. Ive donw EEPROM before. Im talking about the program code.

    Not a programmer. Its a site i found on google that lists the commands PBP supports http://www.rentron.com/PicBasic2.htm
    Is there a better list somewhere?

    So it is possible to overwrite active program memory? Would it be possible to overwrite the whole chip? The only problem i can think of is that the code space is usually bigger than the ram on the chip so that would require multiple serin commands and once it gets overwritten then it doesnt work again.

    If i wanted to write just a little bit of code onto the chip then how does that work? To run it do i just tell the chip to goto the address of the first line or something?

    Ive never programmed a chip to reprogram itself before. It sounds like something that would be very usefull to know
