Modifying Dictionary Objects
Modifying Dictionary Objects
Modifying an object stored in a dictionary is similar to deleting an object. If the object is
never referenced by other objects, the modification is comparatively simple. If the
object is referenced by other objects, then you must first delete and then redefine the
referring objects.
Objects that can be referenced by other objects are:
•
Constants
•
Definitions
•
SPI token types
Objects that are never referenced by other objects are:
•
Records
•
SPI token codes
•
SPI token maps
