I discovered that some words documented in the Gforth manual, like MAX-U (environment wordset) and u/ (gforth-1.0 wordset), are undefined in my installations of Gforth 0.7.3.

Is there something messed up with my installations, or is there
something else (Forth command, installation, Gforth upgrade) to make
such words/wordsets available in my Gforth environment?

MAX-U is present in gforth 0.7.3 and in the info doc's.
You must add ENVIRONMENT to the search order before MAX-U is visible.

u/ is not to be found in the info doc's and not in the executable
in my official installation of 0.7.3. That suggests a later addition.

Is there something messed up with my installations, or is there
something else (Forth command, installation, Gforth upgrade) to make
such words/wordsets available in my Gforth environment?

The manual you are using is not the one for the Gforth version you are
using.

You can find the manual for Gforth-0.7 on <https://www.complang.tuwien.ac.at/forth/gforth/Docs-html/>.

Alternatively, you can install a recent snapshot using one of the
methods mentioned on <https://gforth.org/>.

If you want to use the words mentioned above, the latter course is the
one you want to take. Note that the "environment wordset" means that
the name is intended to be used with "ENVIRONEMENT?", and MAX-U is
already present in gforth-0.7:

The manual you are using is not the one for the Gforth version you are
using.

However if you are on an official ubuntu/debian distribution like me,
the manual and the program agree.
Assuming you have installed it officially. (Mostly 0.7.3).

Thanks for setting me straight. I see I was misreading the manual on
MAX-U, and that it is available in 0.7.3 if used correctly.

I tried installing the 0.7.9 snapshot and now u/ is available as
described.

The only thing that still mystifies me is why a seemingly basic word
like u/ wasn't added until so recently.

The standard has UM/MOD (and that has been in Gforth from the start)
if / does not satisfy your needs.

Actually IIRC we did not add U/ because of user demand, but mainly
because of implementation (speed of U/ vs UM/MOD on various CPUs) and completeness considerations.

I see I should have read Starting Forth more carefully.

Thanks for the background on U/.
