In this particular case I've added the stack diagrams to analyze the program.

Quote:I think I might have had the stack reversed (left-to-right vs. your right-to-left), so that the 'bottom' level is at the left side near the current command, so you can always see the most immediate argument you are working with.

That's just the way stack-diagrams are written in FORTH.
Though I can see your point it would be tedious to reverse the stack and have it right-aligned. I think it's helpful when elements of the stack that aren't affected by a command stay at the same position.
You could write the stack-diagram on the left of your code but then you'll see the result before you see the action.
After a while you just get used to it.

Cheers
