Zone Stamp: How to retrieve Zone Level

[Durval]

Is there a global variable, REQUEST function or any other means of finding out the Zone level, so that I can print it in a custom Zone Stamp?
What I'm planning is to add the Level Dimension Tool functionality (well, kind of...) to a Zone Stamp. Would it be possible?

Possibly, you need the ROOM_BASELEV Global GDL Parameter.

Thank you Laszlo, this is what I was looking for!
