AHEAD

Interpretation:

Interpretation semantics for this word are undefined.

Compilation:

( C: -- orig )

Put the location of a new unresolved forward reference orig onto the control flow stack. Append the run-time semantics given below to the current definition. The semantics are incomplete until orig is resolved (e.g., by THEN).

Run-time:

( -- )

Continue execution at the location specified by the resolution of orig.

Testing:

T{ : pt1 AHEAD 1111 2222 THEN 3333 ; -> }T
T{ pt1 -> 3333 }T
