This also reminds me the THEOLOGY ROM for the HP-71B, with its powerful CREATE ALL statement (the regular HP-71b has DESTROY ALL, PURGE ALL and END ALL statements).
Below is an excerpt from HPX Echange, V1N3p17 May/June 1987

! THEOLOGY ROM !
+--------------+
As the astute noticed, the Quick Reference Guide in "HP-71 BASIC Made Easy"
(pg. 147) refers to the CREATE ALL statement in the THEOLOGY ROM. This
is just one of the many keywords to be found in this huge lexfile. It is based
on a higher source code, which unfortunately this magazine is too small to
contain. But I just have to tell you about CREATE ALL; you are sure to get a
big bang out of it!
CREATE ALL, as the name implies, creates everything. Since this is such an
immense task, it takes about six DAYS (!) to finish, after which the
configuration code works for another 24 hours making sure that what was CREATEd
is indeed good, during which time the HP-71 will appear to have gone into deep
sleep. Of course, CREATE ALL only works if ALL does not already exist. If ALL
already exists, CREATE ALL gives the "File already exists" error. If this
occurs, it isn't enough to PURGE ALL or even DESTROY ALL. The THEOLOGY ROM
has an expanded version of END ALL that does the trick. Proper use of END ALL
is vital, since further action by users who have ENDed is impossible. The
following is suggested: "END ALL @ CREATE ALL" on one line!
If interested in CREATE ALL and END ALL, please look for a subset lexfile
called GENESIS on a future swapdisc! But PLEASE use it carefully!
