Glossary

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" 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@.
