I didn't put too much effort into it. I just single stepped through the original →RPN program and noticed that I had to put everything into a list using: 1 →LIST.
But this made the following check for list obsolete: TYPE 5 ≠. Therefore I dropped that.
And then I had to insert a SWAP so that the operator in the local variable f is added to the head of the list.
Therefore you'd have to ask the developer of the TEACH command.

Thinking about optimizations we might also combine both loops into a single one.
