delete object_id
copy object_id new_object_id
rename object_id new_object_id
These commands handle user defined objects in CRE (blocks, methods, towers)
To remove an object from the workspace, use the delete command; for example
CRE> delete grandsire5
Objects may be copied by using copy; for example
CRE> copy grandsire5 grandsire5b
N.B. towers are not actually copied - this command assigns an alternative identifier to it. However, blocks and methods are copied in their entirety, so making changes to one of the copies will not affect the other.
Objects can also be renamed; for example
CRE> rename fred freda
