How do I convert a string into an expression?

I am trying to convert a string into an expression (an object's instance variable) and use it in a comparision.

This question doesn't really make sense. What are you trying to do, exactly? Why would you need an instance variable to be an expression?

I have 4 instance variables for an object, the names of the variables are for example var0, var1, var2 and var3.

I wan't to check if one of the variables is true or false in a single comaprision block. However, in order to know which one of the instance variables I need to check I have to use this other number that determines it (in my case it's the 'loopindex'.

So, I am trying to construct the variable as a string object.var&loopindex, and then use it to check. But, I don't think I know how to do it or whether it's even possible...

Mmm! Perhaps somebody will contradict me and we'll both learn something, but... to my knowledge it's not possible to do that

I've already tried this, and it's impossible that way. You'll have to find another solution

Suppose none bothered to click.

Anyway. Another way is to use an array.
