How do I Refer to a Instance Variable using an expression?

I know, poor title.

I'm wondering if it's in any way possible to refer to a variable based on a variable expression. For example I have a few variables, object_info_0, object_info_1 and so on...

I'm trying to put each variable's contents into a co-ordinate of an array but from what I've tried I can't write an expression anything like:

object_info_ & array.x

or something along the lines.

You can store the variables values in the array and check the array value instead

for "loop" 0 to object.count - 1

set aray(loopindex("loop")) to object(loopindex("loop")).X

or

for "loop" 0 to object.count - 1

pick object by nth (loopindex("loop"))

set aray(loopindex("loop")) to object.X

Eventualy you can make a previous pick above the loop.

like: pick objects who's instance variable is 1

then it runs only trough those objects

That's what I'm trying to do. I want to create a instance variable and them into the array.

Thanks but I was referring to local/global variables. Even if I referenced an object's instance variable I couldn't do something like:

object.instance_variable_ & loopindex

What I want to do is if I had variables named var_1, var_2, var_3 and so on I'd like to refer to each of those.

Here's an example.

I want to set each X of an array to the value of these variables.

I have nothing to add to this:
