Stringify S I At Init time you can define a stringify-macro in this attribute: anytime the object feels it should draw itself, that macro is executed with one argument: the current Value. The result of the macro is used as label for the object. If the macro fails or it returns an empty string or it doesn't return anithing, Value itself is used.
The macro must be an ARexx-in-line-string-macro designed to be fast. A simple example is:
nb.Stringify = "parse arg val;return 'Value is:" val"

WARNING: YOU CAN'T USE ANY FUNCTION OR SET ANY ATTRIBUTE OR DO ANYTHING THAT MIGHT LOCK THE LAYERS INSIDE STRINGIFY (E.G. YOU CANNOT OPEN WINDOWS, OPEN REQUESTERS OR EVEN SAY THERE!

WARNING: If Max-Min is -1, both at init time or after a set, the class will refuse to accept it.
