Lua debugger set program counter to cursor

["Scott Huber" <scotthuber@...>]

Has anyone written code where you can set the program counter of a
lua_State?  Or does anyone have any hints or guesses on how to do this?

I'm
working on a Lua debugger and am trying to figure out the feasibility
of making a feature where the user can select a line, and set the Lua
program counter to that line.  The scope may be restricted to allowing
this only within the same function or possibly only within the same
block.

In luaV_execute () it updates the program counter, so maybe I
can search back or forward from the current pc for a pc with its line
data populated and check that against the line that the user requested
the program counter to be positioned at.

Any thoughts?

Thanks,
