HasMetaData

Description:              Tests whether a given variable is a dictionary.  Since the default behaviour 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 or not a variable contains a dictionary.

Returns:                    Boolean

Usage:                       Script or steady state

Format:                      RVAL = HasMetaData( dictionary );

Parameters:             Dictionary   { any variable }  { required }  { no default }

                                      The name of any variable to test.

Comments:            Returns TRUE if the object is a dictionary and FALSE otherwise.
