Hello pros!
Today, for the use of pcall, I was trying to take a file, such as "startup" and take all the code from it and put it into a function.
So, for example purposes, could someone give me some code to take all the code from "startup", make that code into a function which can be used in the running program with pcall?
I am not asking to be spoon fed, just for some help.
Is there any way to do this?

This is so simple imma just go with the spoon anyways

pcall(loadfile"/startup")

[MKlegoman357]

loadfile does just that.

local func, err = loadfile("startup") --// Load the file

if not func then --// If program has errors 'func' is nil and 'err' contains the error
  error("There was an error loading startup:\n" .. err)
end

pcall(func) --// Call the function

Thank you! But one question, just for further use, what exactly does loadfile do? What does it return?

it loads a file into memory (os.loadAPI uses load file). It returns a function, just like you asked for; lol.

Oh...
for some reason I thought it returned a string with the contents of the file in it *facepalm*

Thanks for all the help!
