\ It's important to know how forth processes instructions. All programming in Forth is
\ done by manipulating what's known as the parameter stack (more commonly just referred
-\ to as "the stack"). The stack is a typical last-in-first-out (LIFO) stack. Typing:
+\ to as "the stack"). Typing:
5 2 3 56 76 23 65
-\ Means 5 gets put on the stack first, then 2, then 3, etc all the way to 65, which
-\ is now at the top of the stack. We can see the length and contents of the stack by
-\ passing forth the word `.s`:
-.s <7> 5 2 3 56 76 23 65 \ ok
+\ Makes those numbers get added to the stack, from left to right.
+.s \ <7> 5 2 3 56 76 23 65 ok
\ Forth's interpreter interprets what you type in one of two ways: as *words* (i.e. the
\ name of subroutines) or as *numbers*. Words are essentially "symbols that do things".
-\ Finally, as the stack is LIFO, we obviously must use postfix notation to manipulate
-\ the stack. This should become clear shortly.

-\ Lets do a simple equation: adding 5 and 4. In infix notation this would be 5 + 4,
-\ but as forth works in postfix (see above about stack manipulation) we input it like so:
+\ Arithmetic (in fact most words requiring data) works by manipulating data on
+\ the stack.
5 4 + \ ok
-\ However, this alone yields "ok", yet no answer. Typing the word `.` will yield
-\ the result.
+\ This adds 5 and 4 to the stack and then `+` is called, which removes them and
+\ adds the result to the stack. We can see it with `.`:
