Re: Localizing Large Numbers of Variables in a DynamicModule:


Hi,

and

args = {x1, x2, x3, x4}

DynamicModule @@ {args,
     {x1, x2}
   }

does what you expect ..

However -- it is incredible bad style
to make functions with "large number of variables"

The usual way is to break down the task to a large
number of tiny functions. It is well know from other
programming languages that this technique avoid
many local variables.

For example, function foo may call other functions which in  turn call other functions ... until finally the bottom function may need to  access say the variable - x1. Having to  repeatedly pass the entire or selected parts of  the variable space can get unwieldy and impact on the final code's  readability. Thanks.
