 get [the] [long|short] owner of card
get [the] owner of window 

This read-only property tells you the name of the background to which a specified card belongs, or it tells you the creator of a window.

Long owner of card returns the full path name of the background. Short owner of card returns the short name of the background.

Owner of card returns “bkgnd” plus the leaf name of the background.

The window form returns HyperCard if it's a stack or built-in window, or the name of an XCMD if it's an external window.
