POR is an experiment with lexing out a stack based machine.
Native instructions - there are none. How's that for small?
Words that are not understood are pushed onto the stack as text. That should make debugging terribly difficult.
Conditionals are what I'm interested in. Can I program words to accept:
if ... (else ...) endif
It should work that when 'if' is encountered, we test the top of the stack. If the condition is true, we will execute to the else and then skip to the endif. Otherwise, we will execute from the else to the endif.
