The question is really<br />
whether the ANS standard<br />
will be an attractive proposi-<br />
tion to users and implement-<br />
ors. I should think it might<br />
be, given the background<br />
and caliber of people work-<br />
ing on the committee. I am<br />
going to try to obtain a dpANS<br />
document whenever it be-<br />
comes available to the gen-<br />

Subject: Traditional <strong>Forth</strong><br />
Elizabeth Rather writes,<br />
"Traditional <strong>Forth</strong>, for<br />
example, allows the user<br />
to know and make use of<br />
knowledge of what is<br />
'compiled' (or, more ac-<br />
curately, assembled)--<br />
and to exercise total con-<br />
trol over the process.<br />
"Hogwash! What on earth<br />
is this 'traditional <strong>Forth</strong>,'<br />
and what did it 'compile<br />
or assemble'? Did it as-<br />
semble the same thing on<br />
a 6502 as it did on a PDP-<br />
11? If so, how did it run?<br />
And if not, how could the<br />
user 'know and make use<br />
of' that knowledge in a<br />
transportable fashion?'"<br />
To describe what I call<br />
traditional <strong>Forth</strong>, perhaps it<br />
would be wise to repeat the<br />
major texts I have used in<br />
teaching <strong>Forth</strong> (I am not going<br />
back to Kitt Peak Primer<br />
and the various manuals,<br />
<strong>Forth</strong> Dimensions articles,<br />
etc. that I used to actually<br />
learn the languagejust the<br />
printed works that I feel describe<br />
what I am calling traditional<br />
<strong>Forth</strong>):<br />
1. Starting ForCh by Leo<br />
Brodie (published by<br />
<strong>Forth</strong>, Inc!!!)<br />
2. minking <strong>Forth</strong> by Leo<br />
Brodie<br />
3. <strong>Forth</strong>: A Tm and Reference<br />
by Kelly & Spies<br />
I should also list the sys-<br />
tems I have used over the<br />
years, all ofwhich have been<br />
reasonably consistent with<br />
the description of <strong>Forth</strong> given<br />
