Others have made good points. I'm pretty much not using the 16 series anymore. I use 18, 24, and 32. The 18 is close to the 16 but has a nice instruction called movff and has a "file" called WREG. So, you can do movff WREG, SomeRam and movff SomeRam,WREG without having to deal with banksel. I also use the access bank for stuff where I do not want to use movff. But, the access bank is limited in size. Harold --=20 FCC Rules Updated Daily at http://www.hallikainen.com - Advertising opportunities available!
