Not that I know of. The "frame <stack-addr> <pc-addr>" form of the frame command sounds like it should be usable to achieve that, but it doesn't seem to work in that way. I really wonder if it's working as it was intended initially. I guess using that form of the frame command should override/mask the real current values of $sp and $pc? Simon
