Suppose I define a function, called myfunc[a_,b_,c_]:=
several_lines_of_code

How can I call this function in another notebook without retyping
entire function, so that the command

value=myfunc[x,y,z] will give me the desired result?

Do I simply include a Needs command at the top of the worksheet, or
what?
