How to run a m file in a function which is called in another main m file?

I want to Load variables taken from a user in a function. I could think of two ways. 1) I created a m file to take user input ( So I have 3 files- Main m file, Function, Input m file) Now I wanted to run that Input m file in a function which is called in the main m file. How could I load workspace variables from that input m file into the function. 2) To take input in The main m file ( I have 2 files- Main m file, Function) Now I want to load all the variables in workspace in that called function As there are many variables in workspace (approx 20) which are required in the function, Is there any short cut to load all the workspace variables in that function?
