Word routines
|
||
|
|
|
||
|
|
This is the description of all word routine you can encounter
|
||
|
|
in this Forth implementation. That is, a wordref will always
|
||
|
|
point to a memory offset containing one of these numbers.
|
||
|
|
|
||
|
|
0x17: nativeWord. This words PFA contains native binary code
|
||
|
|
and is jumped to directly.
|
||
|
|
|
||
|
|
0x0e: compiledWord. This word's PFA contains an atom list and
|
||
|
|
its execution is described in "EXECUTION MODEL" above.
|
||
|
|
|
||
|
|
0x0b: cellWord. This word is usually followed by a 2-byte value
|
||
|
|
in its PFA. Upon execution, the *address* of the PFA is pushed
|
||
|
|
to PS.
