ansi .6.1.1345
<CORE>
check the environment for a property, usually
a condition like questioning the existance of
specified wordset, but it can also return some
implementation properties like "WORDLISTS"
(the length of the search-order) or "#LOCALS"
(the maximum number of locals) - this is an
ANSI-requirement although I have never seen
someone actually using it but some portable
forth-code may find it useful...
