In the case of a user program which is passed to DOLIST, you can't. It is being run repeatedly within the confines of the single DOLIST step, so when you SST through that command all of the invocations have already occurred.

Oh yay. That could be a bit of a problem if I needed to trace without having understood which commands can't be traced into.

In the end, I did it the old-fashioned way. Anyone want to guess what that uses?
(Hint: it doesn't need electricity, or really a calculator. It just needs a reference manual.)

Yeah, I used paper and pen. I wrote the instructions down, along with the stack, list of vars and directories. It only took one A4 piece of paper to get. Understanding what each instruction helped out when I was writing up the stack, and only impressed me even more about just how useful the AUR is. It also let me figure out how that program posted earlier actually works, and how he got away with the specific commands he used. Nice job, Gilles59, and thank you.
