I can find the data by preforming a read but it is in the 4 digit code which I don't know how to read can any one help me get my pic program back into pic basic???
Thanks Raybel

Hi,

how can I retrieve the data back into pic basic so I can edit it
I'm sorry to say it but you can't.
You can read the .hex out of the chip and possible run it thru a disasembler to get it from hex to assembly language but that's about as far as you're going to get. There is no way to retreive the original PBP source.

Thanks Henrik
I was afraid of that ,
one more question is there a way of copying and saving the file at least I could make more of them
right now I only have one and I need a few more even if I cant edit it
or if it was dissembled could I use that file??
Thanks again
Rabel

If you just want to make more, you don't have to disassemble it - you just read the file off the chip and use that to program more.
