hiya,

	After the success of my routine to convert a string to uppercase (it
was fast wasn't it :-) and after a couple of requests to post a version that
did the conversion the other way (i.e. from upper case to lower case), I decided
to write the other version.  It should run as fast as the first program for
most strings (the pathalogical case is different and it involves a multiply
sign this time) and it is also very small.


	This program checks for the existance and the correct type of its
agruments and doesn't modify the passed string in-situ (this means things
like undo will work and that the program is in general, well behaved).
Any non-profit usage of this piece of code is permitted.  People, who want
to use this in a for-profit venture should either contact me and get my
permission first or write their own version (probably the latter if they
are serious about it ;-)


	Comments anybody?


I include ther code in ASC-> format.  This string is 182 bytes long
and has a checksum of # 7210h.  The object you get on the stack after
running it through ASC-> has a size of 85.5 bytes and a checksum of
# A308h.

At least it isn't one of those really chunky looking ASC-> programs
several pages long ;-}
