Nice to see you on this website! I have 3.14159 stored in variables PI and
13952. I open up braces, press the soft key below [PI], below [13952],
followed by [ENTER]. I now have {PI 13952.} on the stack. This is not
what happened before. Notice 13952. versus 13952. Naturally ORDER
generates an error.

Could you simply use something like |3952 (first char: bar) or l3952 (first char: L)? I believe those names would give you less trouble in the long run. The bar looks a bit closer to a "1" than the "l" does, but there could be other places it shows up where you might choose one over the other.

Another potential issue to watch out for with ORDER is that you don't invoke it with a list that would end up attempting to move the same program that called it. In that case, you get a rather ambiguous "Syntax Error" message. While it makes sense that you can't move a running program, the message itself isn't particularly helpful in figuring out what went wrong.
