Symbol Table Class
Symbol Table Data Structure Summary: The Symbol Table is a data structure that stores Name and Value pairs. It can store multiple pairs which have the same Name. This data structure can also be used as an an associative array. When asked to lookup a duplicate Name, the Lookup function always returns the Value that were most recently added.

Hash Tables: The HashTable data structure is usually more efficient than the Symbol Table data structure because it its algorithms generally perform faster lookups. This Class can be more efficient than the HashTable data structure when the most-recently-added definitions are also the most-frequently-retrieved definitions.
Examples: Since this Class represents a data structure, you must DIMension a instance of this Class for each Symbol Table you would like to create. The following line of Visual Basic code will create a Symbol Table:

v1.3 Change: 1. This Class has been fixed to support the storage and retrieveal of Object and DataObject type Values (variables with a datatype of vbObject and vbDataObject). See the other BugFix notes within this Class for a list of the individual Functions and Subroutines that are affected by this change.
v2.0 Changes: 1. Changed a few of the arguments so that they can no longer be Null or non-numeric. They are still Optional though, so they can be missing. See the Functions below for the details of this change. 2. Embedded a local copy of an Entisoft Tools routine within this Class so that this Class is no longer dependent upon routines in any of the other Entisoft Tools Classes.
