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.
I really don't understand what you are trying to achieve here ... but
perhaps you will find some inspiration in this:
With[{args = {x1,x2,x3,x4,x5}},
DynamicModule[args,
oo@@args;
oo@@args;
...
]
]
With[] will just subsitute {x1,x2,x3,x4,x5} for every instance of args
before it evaluates its body.
