These primitives allow you to list elements of Prograph programs. Many of these primitives accept strings as inputs to specify classes and attributes. A string specifying a class must be the name of an existing class, and a string specifying an attribute in a class must be the name of an attribute in that class. Some System primitives find comments associated with Prograph elements. If the element has no comment, the result is NULL.
