hello.
as i was thinking about a real time path list, i sudentlly think have the idea to use the push and pop operations to do that.
but then, it will act on a secondary stack.



then, use the normal stack for basic operations on push & pops during code exustions.

and use the secondary stack as a path, updated each time we call or ret.
then, it will be easy to know the exact location of curent code or item...

someting like that.

but i wonder how i can do it efficienttly, and securelly...

edfed,

This resembles the concept from FORTH: separate data and return stacks. Nothing really complex, you may use following (straightforward) macros, assuming that return stack is pointed by es:bp: Another technique is to reserve one register as link register which will contain return address upon function entry, RISC style. In this case, called function is responsible to save/restore that address (if it needs that register for something, e.g. to call another function).
