Simple question:
Is there any way to convert a string to a variable?

Umm, not sure that's a simple question. You have a variable that say contains the string Mystring and you want to create a new dynamic variable called Mystring? If that's the case I would guess the answer is no.

What i'm trying to do is to open a file, say My file.txt that could look like this:
13
23
4
15
and so on...
Then pick a number at a time using Loop, Read, adding that number to a variable (Sum) and finaly showing the sum of all those numbers!

Ok, based on your question you already know how to read the file, in your loop just add the strings

Myvar += %A_LoopField%

Not sure if the var is right but you should already know that part.

Although it's not related to the question at hand, you can create a variable dynamically. The method is the same as that for creating arrays. The simplest example is probably:

Dynamic = MyNewVar
%Dynamic% = Value

Cool! Didn't know you could do that!

Jonny got it right
but the test is not necessay. Ahk automatically assignes the var as a number. if its not numeric it simple returns a zero
ie.
12
3
23
some text
3
4
; a blank
3

returns answer 47 Et voila!

Eh, show me up, will you? Well then, take this!



Re-optimization! The brackets aren't necessary for one line!

That return isn't entirely necessary either, since AHK has "fall-off" support, so this is a three-liner.

I can't believe I didn't see that return. Well spotted sir. Mind U I didn't write the script did I, only corrected it.

I actually meant the return at the end. This is a valid AHK script:
