Version 415 of POP11
====================
.sp
There is a new version of the POP11 system running.
This new version is incompatible with the old in the following
respects:
.in3
.ti0
!)#The DATABASE package has changed.
In the old version of this package items were stored in a variable
called 'CONTEXT' which could be cleared using the function 'DATABASE'.
That is:
 	: FUNCTION DATABASE();
 	:	[] -> CONTEXT;
 	: END;
.br
In the new version the items are stored in the variable DATABASE and there
is no function to clear it, that is if you want to clear the DATABASE
one executes:
 	: [] -> DATABASE;
.br
Furthermore, the function SHOWDATABASE no longer exists. Instead one uses the
print arrow, thus:
 	: DATABASE =>
.br
If there are many stored items this will produce untidy output, so one
might as well use the pretty print arrow, thus:
 	: DATABASE ==>
.sp
.ti0
2)#The function 'LENGTH' now works on words, strings etc, eg
 	: LENGTH("CAT") =>
 	** 3
