> The motivation for this is that in constructing a complex interface the number of varfiables and functions may get quite large and further, these variables may also need to be accessed in another function that is nested more deeply . 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.
You can splice in the contents of the variable args into Module or
DynamicModule by using Evaluate:
args={aaa,bbb,ccc,ddd};
Module[Evaluate[args], ddd]
