Actually, the instruction set differences between the 12-bit and 14-bit cores are that the 12-bit cores do not have the following instructions: ADDLW SUBLW RETFIE RETURN Douglas Wood Software Engineer spam_OUTdbwoodTakeThisOuTkc.rr.com Home of the EPICIS Development System for the PIC and SX http://epicis.piclist.com -- http://www.piclist.com#nomail Going offline?

On a 12-bit core PIC, use RETLW (it's the only "RETURN" type instruction available). Douglas Wood Software Engineer dbwoodspam_OUTkc.rr.com Home of the EPICIS Development System for the PIC and SX http://epicis.piclist.com {Original Message removed}

How do I return from a CALL??? I think the closest equivalent is 'retlw'.

You use RETLW, so you have to corrupt W when returning.

Alexandre, If you'd like, I can send you a chart that compares the (currently) four different instruction set types and which flags each instruction modifies.

Fellow PICLISTers: Thank you the your responses about my PIC Instruction Set Comparison Matrix. You can access the matrix from my web site at EPICIS.PICLIST.COM A link to the matrix page appears on the left side. If any one would like a poster-size (13"x19") printed copy, suitable for framing (or lining your bird cage), please contact at my email address shown below. Be sure to let me know your mailing address. Also, while the poster is free, depending upon where (in the world) you live, I may ask for a donation to help defray shi[[ing costs.

Sorry, I forgot to mention that the availability of the Instruction Set Matrix is subject to when James can find time to load it and some other web page graphics onto his server for me.

The link gives me a 404 error. The path http://www.piclist.com/techref/member/DW--RA4/ is ok as the index.htm pages loads. However PICISM.HTM dosen't seem to be there. Regards Mike > {Original Message removed}
