Are there any LISPs to show a transparent menu to monitor variables in the background?

Hi, 

I am still quite new with Autolisp and am not even sure if what I am going to ask is possible! 

I run Carlson Survey on Autocad and work with Coordinate systems all of the time. I also frequently switch state plan coordinate systems and accidently working with the wrong one can be a costly mistake! 

I would like to create an autolisp that would essentially show a transparent status bubble actively in the background (lets say at the top right of my workspace) within my working drawing saying either "Louisiana North" or "Louisiana South" as the current zone. 

I have identified the variable CS_PROJ_ZONE as the active variable that determines the zone. 

Are their any open source lisps that display a bubble menu in the background displaying a variable? 

Thanks!

One easy way would be to use System Variable Monitor which is built-in to AutoCAD.

Type _SYSVARMONITOR on the command line. In the upcoming dialogue, click on the Edit List button and add your intended variable. Type your preferred value in the Preferred column. Remember to check the Notify when these system variables change checkbox.

Hope this helps.

Hi Yasir,

This would be a very nice solution except that it is limited to monitoring system functions only (as far as I can tell). It does not have the variable I am trying to monitor which is CS_PROJ_ZONE as this is a Carlson specific variable.

Is this  item you are monitoring changing throughout your editing session?

This comes to mind (setvar "modemacro" "current world co-ord")

Need a dwg and some idea of where CS_PROJ_ZONE is hidden then may be able to use a field.
