not “really”. if you send the message  and omit some parameters they will just be emptied out. so if you have a send and receive in your numberbox, they will be deleted if you send a param message and don’t declare them again. i don’t know if there is a way to leave them unchanged (other then declaring them every time you send the message)

Cool. The param message works fine if you don’t give it the full param list as well aka [param 0 0 1 hello<.

Subject: Re: [PD] numberboxes range


Actually, this is possible.

Send this message to a number box:

[param f f f s f s s(

where f is float and s is symbol according to the following syntax:

[param   <width>   <lower-limit>   <upper-limit>   <label>   <position>   <receive-label>   <send-label>l(

This works with symbol atoms too.
