that's very easy, just get the number of elements from the array's  
pointer, and send it as [max $1( to the nbox (or whichever command defines  
the limits, I don't have Pd open).

I think not from the gui. Unless you enforce it programatically: route the  
"change" output from the [struct] in the template, and use it to force the  
maximum number to a [set] object. Like:

[struct drawnumber...]
|
[route change]
|
[50(  (assuming 50 is the current max number)
|
[set drawnumber...]


In a parallel part, the current pointer gets and sets the maximum number  
of elements (now at 50)

Look at the current help file for [drawnumber] for more details.
