>Also l am only jumping about 10 bytes or so so l am definitely within = the >256 byte barrier... but do those 10 bytes cross a 256 byte page boundary. that is to say if = the start of the table is at 1F8 hex, and your table is 10 bytes = (decimal) long, then the end of the table is past a 256 byte page = boundary, and any attempt to access entries 9 and ten will actually = result in your code going to locations 000 and 001 hex respectively. -- http://www.piclist.com#nomail Going offline?
