short iniread () and array question (hypothetical )

[markyrocks]

So I like to use ini's to read and write and other various purposes.  I wrote a function earlier that I didn't test but I'm wondering if it's going to work in theory.  

So say below is my ini

[sec]

numdata=3

data1=1

data2=2

data3=3

;would this allow a potential user to add more here based on the following? 

$num=iniread("filetxt","sec","numdata","")
Dim $array[$num-1]

For $x=0 to ubound($array)-1
$array[$x]=iniread("file.txt","sec","data" & $x+1,"")

I've thought about this pretty thoroughly as you can see.  I'm just curious on thoughts.  I think its pretty sweet.   Obviously I don't have any fail safes in there for unforseen events.

Well yes it will let you do just that. However it won't got all the data#'s because you reduce it when Dim'ing the $array array and then again after ubounding it.  So it will just read data 1 and 2, not 3.

But I think you are just asking if the key name can be a variable combined with a string and the answer is yes.

When using INI's i prefer IniReadSection. Deleting numdata=3 in your INI before using it in this small script_

#include <Array.au3>
$array=IniReadSection("filetxt","sec")

_ArrayDisplay($array)

has a resulting array with all what i need.

 $num=3

Dimming $array [$num-1]

Would give 3 slots 0,1,2

Wouldn't the result of ubound(array) also be 3? 

Going for $x=0 to ubound ($array)

Would be 0,1,2 3.  Going out of bounds?   

 

I'm going to have to do a small test.  Half the time I'm on this forum I'm on a smartphone so I really can't test anything. 

 

Edit: just checked it out.   You are indeed correct sir.

@markyrocks, you understand what Dim does and the caveats surround it?

[markyrocks]

Apparently not.  Idk why I was under the impression dim was used to declare an array.

From what I gather in the help file dim is used to declare a variable locally but give it global scope?  That's kinda beyond my mind.  I always declare all globals at the beginning of my scripts.

It might be good to get your mind around it in the future. Globals are really awful and can lead a lot of time debugging. Try and keep your variables declared in the lowest scope possible.
