Kangaroo method
The “lone” DOES> is used for the creation of only one word rather than for the creation of a category of words. simple example in noForth
create .DAY ( n -- ) s" SunMonTueWedThuFriSat ? " m, align does> swap 7 umin 3 * + 3 type ;
example in noForth
create : assembler ip push w ip mov next forth \ DOCOL does> create here cell- doer! ] ; \ Action
or
:noname does> create here cell- doer! ] ; create : assembler ip push w ip mov next forth execute
“faraway” DOES> for forward references in metacompiler
create : assembler ip push w ip mov next forth ... \ many other definitions TELL : TO-DO: create here cell- doer! ] ;
literal pool in assembler words with CODE>
code !RP0 ( -- ) ramadr: RP0 , \ register w points to this literal code> day w ) ldr, day day ) ldr, rp day mov, next, end-code
