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 words *code link*. For example,
|
|
the label "PLUS:" in this unit is a word reference. Why not
|
|
refer to the beginning of the word struct? Because we actually
|
|
seldom refer to the name and prev link, except during
|
|
compilation, so defining "word reference" this way makes the
|
|
code easier to understand.
