Flow
|
|
|
|
Note about flow words: flow words can only be used in
|
|
definitions. In the INTERPRET loop, they don't have the desired
|
|
effect because each word from the input stream is executed
|
|
immediately. In this context, branching doesn't work.
|
|
|
|
(br) -- Branches by the number specified in the 2 following
|
|
bytes. Can be negative.
|
|
(?br) f -- Branch if f is false.
|
|
( -- *I* Comment. Ignore rest of line until ")" is read.
|
|
[ -- Begin interpretative mode. In a definition, words
|
|
between here and "]" will be executed instead of
|
|
compiled.
|
|
] -- End interpretative mode.
|
|
ABORT -- Resets PS and RS and returns to interpreter. (cont.)
