Ah that explains it!

I didn't try RCX Code, I wasn't that keen on it and also it wouldn't run on my
NT workstation. I moved straight on to NQC and more recently have been trying
RoboLab.

That's why I didn't get the reference.

Thanks,
Conrad.

Conrad,

LEGO does refer to series of commands as 'stacks'.  This comes from the
Robotics Invention System RCX Code interface where a program is a
literal 'stack' of instruction blocks; those who haven't used RCX Code much
wouldn't recognize the reference.  I honestly don't know why they
chose 'stack' either; it's caused many people confusion.  Although I can't
think of an appropriate alternative term to use in its place.  Hmm.

Perhaps someone can clarify this for me...

I've been looking at the LEGO P-brick Script code language documentation that
comes with the RIS 2.0 SDK PreAlpha.

I was initially confused by the numerous references to program stacks.

Does 'stack' here simply mean a series of program instructions? It seems that
it must.

It's just that in my limited (26 years) experience of programming, 'stack' • has
always meant a data structure and not code.
