Bummer, I was afraid this was too good to be true. :(

I'm sorry, I explained that poorly (and from memory).

I am using JS_SetInterrupt() for my scripts, so I can step through
them and do a lot of behind the scenes stuff (as needed). One of the
passed params is: jsbytecode *pc

Is it possible, from here, to get the source line of code, without
going back to the source file manually and moving down X lines and
grabbing the source? (This is not possible in my application.)

I will check out the JS debugger files, and see if I can garner
anything from there, but I seem to recall trying this once before..

Thanks Brendan!
