Hi, im new to PIC's, i tried to assemble the 615 aplication note from the MIcrochip book, and when i did, all the lines came out with errors or warnings, i have to say that i received the 16B (not 16B1) as a gift and the assembler version is MPALC 4.14 maybe the assembler is too old???, or is it the source code? Thanks, take care everybody.
