"How to get a robot with a "frame-cycle program" start on a getVar('XXX') command?"

That I look for is a way to start ,for example this robot in the link, when a "getVar('XXX')" command is 1...
...and when the program is finish should it wait for a new signal from "getVar('XXX')".

Sorry for my bad english...

Hope that someone understand
