Is it possible to poplogfolder back to root or know the indentation index?

I couldn't find any built in way to do it.  You could try incrementing a counter every time you do pushlogfolder and then have a routine that loops up to the counter and just does poplogfolder to get you out of the indent, which you would then run right before a new DDT.

I'm not completely clear on what the problem is or what you are trying to accomplish, but see if this link will help.

If this doesn't help, can you provide more details on what you are attempting to do?
