Execute lisp automatically while a command is running?

Hello,

I run a vertical product.it has a command that creates room space with closed polyline on layername.i need to copy to clip automatically

the text (which represents the room name) found inside this closed poly-line which is on the layer "layername".

No answer, difficult i think.

I ask in other way.

Need reactor to trigger a custom command (example copy2clip command) at the end of special closed polyline command on specific layer "layername".

There are many examples of command reactors floating around. Get something going and people are more inclined to help. Also, an example helps.

Thank you alanjt,
