switch case question

[Mark Swindell]

I have a global variable gTimedTest

Depending on whether it is empty or not I want to do different things  
in a handler

How do I write this to make it happen with a switch control structure?

switch gTimedTest

case empty
stuff
break

case not empty
other stuff
break

end switch

The above doesn't work... what is the proper syntax or approach?

Thanks for your help,
Mark
