its complying ok except the port setting is strange i send FE instruction : is ther a paging issue that i should keep in mind i know it is some kind or paging problem i am setting a reg in second page : the mem asign exceptions in the mtu header seems ok unless im skipping a mem block:) all that being said : i have the 16f630 working with a few excetions rules in interperter c code : do you have a discription on the mtu pcu on mem allacation ; im thinking i have a mapping problem : if you would like to see that section of table i can send it;

thanks
