How to change the level of AX info messages

In Dynamics AX 2009 I am trying to determine the level of indentation of an info message. What I want is something similar to this:

Prefix
    Info1
    Info2
Prefix2
    Info3

I found this:

But don't want to use a loop, so I thought something like this might work:

setprefix("Prefix");    

{
    info("Info1");
    info("Info2");
}

setprefix("Prefix2");

{
    info("Info3");
}

But it doesn't. Is there a way to do this in x++, and what are the rules as to what indent level is currently active?
