copydef
COPYDEF newname oldname
command. Makes "newname" a procedure identical to "oldname".
The latter may be a primitive. If "newname" was already defined,
its previous definition is lost. If "newname" was already a
primitive, the redefinition is not permitted unless the variable
REDEFP has the value TRUE.
Note: dialects of Logo differ as to the order of inputs to COPYDEF.
This dialect uses "MAKE order," not "NAME order."
