Indirect addressing....

The input command takes arguments of the form {varname, ....}, where varname is a variable name. Then the function is able to assign values to that variable.
How can I create a function that can take such an argument. I understand how, with the TYPE and SIZE functions, the input function can process all the other arguments, but I can't figure out how it's able to assign values to the variable names passed in the list.
The input function takes a list as it's argument and the variable name is in a sublist.
Anyone know how it does this and if this is even possible for a user's function to do?
Thx
