Used inside a colon definition that itself uses CREATE, DOES>
|
||
|
|
transforms that newly created word into a "does cell", that is,
|
||
|
|
a regular cell ( when called, puts the cell's addr on PS), but
|
||
|
|
right after that, it executes words that appear after the
|
||
|
|
DOES>.
|
||
|
|
|
||
|
|
"does cells" always allocate 4 bytes (2 for the cell, 2 for the
|
||
|
|
DOES> link) and there is no need for ALLOT in colon definition.
|
||
|
|
|
||
|
|
At compile time, colon definition stops processing words when
|
||
|
|
reaching the DOES>.
|
||
|
|
|
||
|
|
Example: ": CONSTANT CREATE HERE @ ! DOES> @ ;"
