-PropertyDataEdit from inside a reactor?

[mr_nick]

I'm currently trying to devise a bit a code to manipulate Property Set data but have hit a bit of a wall. I can attach a property set and read it but I'm having trouble editing it via lisp and more specifically from within a reactor. The only method I have found for editing the property set data is by using (command "-PropertyDataEdit"....) but obviously it's not possible to use 'command' within a reactor.

Is there another method available to edit the data that I can use within a reactor? All I want to be able to do is pass a simple text value to a named key but I'm stuffed if I can suss it out.

Thanks in advance.

Which version of ACad is this? I can't find that command in mine. Is this a vertical like ACA/C3D/etc? If so I think you might have problems with obtaining it through lisp (even using vla methods).

I'm using ACA 2012.
