Hi all,

I wonder if I aim to code based on a single \*.jl (without any external modules etc) if I could move the function definitions at the very low end of my script. Coming from Fortan I used to work like that which made my code appear much cleaner. Can I achieve a similiar behavior in Julia ? So that say the compilation order is changed ?

MWE:

```julia
# Input
x = 10.0;
y = 20.0;

# Output
zsum = mysum(x,y);
zprod = myprod(x,y);
println("sum:", zsum);
println("prod:", zprod);

#############################
# Collected Functions
function mysum(a,b)
    c = a+b
end 

function myprod(a,b)
    c = a*b
end

```

Thank you in advance for your support.

I don’t think you can, although Pluto notebooks work that way - they have n execution order of cells which is independent of the display order, and many people use this to do exactly what you describe here.

Code is evaluated sequentially, so functions need to be defined before they are called.

Here are some alternatives:

1. Place your functions in another file and `include` that file at the start of your script:

2. Place your script in a function and call the function at the end of the file (or from the REPL after `include`ing the file):

@ceysa75 You can use Stevens solution and then try this:

> Hello! Not a question per se, more looking for some feedback I suppose. So by googling a bit, I came around and saw that it is possible to call a macro called Base.@locals, which if you use it inside of a function, you can make it return all variables inside of the function as such: return Base.@locals I have a need for this right now (or atleast I think I do), is there something I should be aware about when using this? Kind regards

This should make it possible to develop in a script, getting the performance boost of a function and then being able to extract everything from the function easily.

Kind regards
