Controlling icon placement?

Hi,

I'm using xterm and aixterm with Mwm on AIX, and having trouble controlling icon placement when minimising windows. Basically when I run an xterm or aixterm I want to be able to specify where the icon will be if minimised.
The man page mentions the "#geometry Geometry" option to aixterm, but despite much playing around I can't get it to actually make any difference.

Any advice or examples please?

Thanks very much!

David

From the xterm man page:

That last sentence could stand a bit of rephrasing. I am not aware of any window manager that pays the slightest bit of attention to this resource.
