Thanks Rick to explain me the use of VALUE.
I prefered to use a variable and to add a private method
to handle the content of variable.

I added KMAP, an associative array implementation (string to word),
and KSTRING, an object porting from a Paysan's implementation
of string.

I hope it's useful to someone.

Ciao,
Alberto
