Determine how much xdata space is still available for an entity.
This function reports the amount of xdata (short for extended entity
data) space still free in the entity identified by entity-name. All
entities in progeCAD have 16KB (actually, 16,383 bytes) each to store any
kind of user-defined data. This function tells you how many bytes are still
(setq txt (entlast))
<Entity name: abc123d4>
NOTE Use this function before you add xdata to the entity to verify whether or not the entity still has xdata room.
