Archive Retrieval

The current Archive Functions in the PI-API use arrays of data to hold returned data. This model works well if the data types can be conveniently represented in array form.

With the introduction of string-valued points, this changes. It is difficult in the C language and in Visual Basic to create and populate an array of string values, since the strings are generally not of the same length, and the length is not known in advance.
