Serial and interrupt

[test153]

12f683 is 8 pin device and has twice the flash memory available.

Thanks for the tip, but I have already bought the other one - as I said to late to change my mind. Anyway i've been doing some diggin and I'm going forward with the ASM serial routine part. There's only one little problem - the code I'm using gives me a "Symbol previously not defined" error. How do I setup variables so I can write to them inside the asm code and reuse them in picbasic?
