-
- Stack notation: "<stack before> -- <stack after>". Rightmost is
- top of stack (TOS). For example, in "a b -- c d", b is TOS
- before, d is TOS after. "R:" means that the Return Stack is
- modified. "I:" prefix means "IMMEDIATE", that is, that this
- stack transformation is made at compile time.
-
- Word references (wordref): When we say we have a "word
- reference", it's a pointer to a word's *code link*. For example,
- the address that "' DUP" puts on the stack is a wordref, that
- is, a reference to the code link of the word DUP.
-
- PF: Parameter field. The area following the code link of a
- word. For example, "' H@ 1+" points to the PF of the word H@.
