Is it possible to change the parameters of a .m file from a GUI?

I am trying to change a string variable of a .m file from an input from a GUI. Is this possible? Can you manipulate code from a GUI?

Are you trying to change the code inside the script, function, or class file itself? Would making the code a function (if it isn't already) and passing the parameter as an input argument when you call the function sufficient? That would be much easier.

Yes, I am trying to change the code inside the script. So far, I have a GUI that allows the user to browse for a file. I want the script to read the filename that the user chooses in the GUI.
