Write functions.
Instead of writing/copying code into lots of different locations, write a function to perform each task and call it from each location where it is needed.
Scripts are great for trying something out or for playing around with some data, but if your code is going to hang around for more than a day then turn them into functions. Functions are also used to allow code to be written (and maintained) in one location, rather than repeating it everywhere.

You can define arguments if you need them, but actually functions don't need input or output arguments at all:
function myfun % <- see, no arguments
... do something
end
Note that each function has its own workspace. If you are planning on passing any values between workspaces then passing arguments is the most efficient way of doing this. Nested functions are also very efficient. Do not use globals (there are plenty of discussions on this forum that will tell you why global is a bad way to program).
