Dear lord of the autohotkey realm.
Can we have normal arrays soon? Records maybe? Some other way to store, pass and return more complex data types (byval or byref) ?
I promise to be a good boy forever...

What makes a "true array"? the fact that the contents of the array presumably exists in the same memory address block? What's the big deal between the two examples below?
Array[i] = test
Array%i% = test
zomg! I can't stand how wide percent signs are... they must be square-braces or I'm not playing with you anymore!

i think what the user is lookin for here is some of the other things that come with arrays
multi dimensional arrays and the ability to get a count of items in the array as well as the ability to stor other than strings and numbers oh i dunno objects but then ahk is not an OOP language

Multi dimensional array...
Array%x%%y%%z% = test
same as Array[x][y][z] in other languages.
You can keep your own count. Most languages don't keep count for you, and those that do are slow.
AHK only has string/numeric values, as you already pointed out.

It is not a question of true arrays, and not a question of multi dimensional arrays.
AHK does not have ANY arrays, not to mention "true arrays"
AHK has variables, and it allows you to use other variables as a part of the variable name. Thats it.
Array is a self contains unit of information that can be referred to by using one name. It can be passed from one function to another for further manipulations.
The Item%A_Index% variables are very comfortable in AHK - it makes it very easy to do a lot of things, but it cannot be a replacement to arrays.
If you are doing a short script (lets say under 1000 lines), this is sufficient and there are workarounds for any problem.
But when you start having longer scripts, with many functions, and many data types, it gets out of control rapidly.
If you want to pass full arrays from one function to another, you have two choices in AHK (maybe more, but these are the obvious):
Make the "array" global, and by this you may have to make your function's completely Global, unless you want to declare every item in your array.
or
Compress the array into one string ("1,2,3"), then decompress it inside the function (StringSplit), then do your thing on the array items, and compress it again into one string in order to return it.
Of course, the caller will also have to decompress the full string again, and put it into array items.
Thats labor intensive, thats messy, thats not how it should be done.

You can pass an array to a function just as easily as creating the array using dereferencing. You will need to practice with this.
| Code: | start:
n := 1
myarray%n% = hello world ; or simply myarray1 = hello world
myfunction("myarray") ; notice the quotes, you're passing the name (aka, pointer) of the array.
msgbox % myarray%n% ; what strikes me is that this works without Global prefix in the function.
msgbox % myarray1 ; again, just play with it until you get the nack.
return
myfunction(thisarray)
{
msgbox %thisarray%1 ; prints "myarray1"
msgbox % %thisarray%1 ; prints "hello world"
%thisarray%1 = goodbye
}

Thank you for trying to help, but I am not looking for answers.
I know all this, and this is not a solution.
Your code works only because all your items in Start: are global.
What you did was in fact my first solution from the previous post - global.
This will not work here:
| Code: |
Start()
Return
Start() {
;Global ; Only if this is uncommented, this will work
n := 1
myarray%n% = hello world
myfunction("myarray") ;
msgbox % myarray%n% ; This worked because all variables are global in a subroutine (Label)
; This will not work now, since we are in a function (i.e. all Local)
msgbox % myarray1 ; this will not be goodbye
}
myfunction(thisarray)
{
msgbox InFunction 1: %thisarray%1 ; prints "myarray1"
msgbox % "InFunction 2: " . %thisarray%1 ; does not print "hello world"
%thisarray%1 = goodbye ; does not effect the array
}
|
What AHK has is similar to a partial implementation of associative arrays (hash) - only there is one thing missing to make it be considered as a more complete implementation, and this is the ability to treat it as one unit, as I mentioned earlier.
Array%FirstName% := "Name"
Array%LastName% := "Last Name"
So far so good, but this should also AUTOMATICALLY create the following two variables:
Array - which should contain the above two - this way we will be able to pass it to functions as one unit
Array.Count or Array0 or anything else that will include the item count and will be updated AUTOMATICALLY whenever a new item is added.
Anyways, thanks for trying to assist, but I was just praying

Ofc Icarus, we all want that.
Language without basic concepts as arrays can never be good. "Conceptual arrays" as we have them now are just poor mans solution.
