(See the best response by FKI.)
Code:
mob
    player
        proc
            test()
                var/x1 = 5
                //...
                x1 = 6
                world << "[x1]"


Problem description: I have a variable x1 of a function test() with an initial value of 5. Somewhere in my code I want to make that variable have a value of 6, permanently everytime the function it is called. But the above code keeps printing 5. How can I fix its scope?
Thanks

You could make it a global variable (and constant, since you mentioned having it be permanent):

var const/x1 = 6

mob/player/proc/Test()
    world << x1 // Always 6.

mob/player/proc/Test2()
    world << x1 // Also 6.

The static keyword is also an option:

mob/player
    proc/test()
        var/static/x1 = 5
        // ...
        x1 = 6


The second time test() is called, x1 is still 6.

Probably not the best way to solve this problem but, you could try putting a sleep(1) before the output. That way the variable should have more then enough time to switch before outputting.

mob
    player
        proc
            test()
                var/x1 = 5
                //...
                x1 = 6
                sleep(1)
                world << "[x1]"
