LOADED is a special VOCABULARY - it will list all the available
wordsets and other MARKER words. The LOADED vocabulary has
the advantage of being always linear, so that all destroyers
are run in correct order. Quite a few of the internal pfe routines
do announce the recources here that they grabbed once, so that a
simple FORGET can make sure everything is cleaned up correctly.
this is a PFE specialty invented at Tektronix, try LOADED WORDS
to get a list of loaded wordsets, and LOADED FORGET MFORTH.O
to unload a specific module loaded with LOADM
