6.2.0700 AGAIN CORE EXT
Interpretation:
Interpretation semantics for this word are undefined.
Compilation:
( C: dest -- )
Append the run-time semantics given below to the current definition, resolving the backward reference dest.
Run-time:
( -- )
Continue execution at the location specified by dest. If no other control flow words are used, any program code after AGAIN will not be executed.
See:
Rationale:
Typical use:
:
X
... BEGIN ... AGAIN
... ;
Unless word-sequence has a way to terminate, this is an endless loop.
