Dictionary Creates a database-like storage structure that provides efficient addition, retrieval and removal of information linked to key values.
DictionaryCopy Create a new dictionary with contents identical to an existing dictionary. It is expected that this function will be used rarely, since in most cases it will be more efficient to hand off a reference to a dictionary rather than build a duplicate of it.

GetNextKey Allows a linear search through a dictionary in place. i.e. without copying the contents to an array.
GetVarMetadata Every variable object contains an embedded value. This function is used to retrieve those values.
HasMetaData Tests whether a given variable is a dictionary. Because the default behavior of most operands and functions on dictionaries is to return just the value of the dictionary’s root, this function provides the only means to determine whether a variable contains a dictionary.
IsDictionary A synonym for HasMetadata. Tests whether the parameter is a dictionary.
ListKeys Returns an array of all keys used within a dictionary. It is expected that this function will be used primarily in the context of metadata (extended information attached to a variable). ListKeys also enables you to discover what is in a dictionary.
MakeDictionary Create and initialize a dictionary with one line of code
MetaData If used with a variable which is not currently a dictionary, this command attached meta data to that variable, thereby creating a dictionary object. The primary purpose in this case is to provide a means of associating extended data with a variable.
RootValue Retrieves the root value from a dictionary. This function will always attempt to return a value that is not itself a dictionary. If the value stored as the root of the given dictionary is also a dictionary, this function will return the root value from that second dictionary. Should all root values be other dictionaries (which would imply that the dictionary at the end of the chain must actually be an earlier dictionary) then RootValue will traverse the chain until it finds a root value which is an earlier dictionary (i.e. the end of the chain before it loops back) and will return that root value. This is the only situation where the command will return a dictionary as the result.
SetVarMetadata Every variable object contains an embedded value. This function is used to set those values.

If the value stored as the root of the given dictionary is also a dictionary, this function will return the root value from that second dictionary. Should all root values be other dictionaries (which would imply that the dictionary at the end of the chain must actually be an earlier dictionary) then RootValue will traverse the chain until it finds a root value which is an earlier dictionary (i.e. the end of the chain before it loops back) and will return that root value.
