A character set is employed which includes beginning delimiter and ending delimiter characters such that data in the form of structures and substructures therein can be nested to any level. One or more cursors are employed to specify storage locations between structures and substructures in which additional structures or substructures may be added. If data currently resides at that location it is read out and restored at new locations. When a structure or substructure is deleted, that space is allocated to other structures or substructures. In this manner, nested fields can be expanded or contracted as required. | |
