A previous section in this book introduces .NET generic types and describes how to reference them as constructed types in ABL by substituting the type parameters (see
Referencing.NET generic types). For example, .NET supports a generic sorted list object that allows you to create a sorted list of key/value pairs, where the value of a specified type is sorted by the key of a specified type. So, to define an object reference to a .NET sorted list consisting of
System.String keys and
System.Int16 values, you can code the following ABL statement:
In this example, the generic type name is constructed by substituting the ABL primitive type, CHARACTER, for the key type parameter (first Tparm) and the ABL AS data type, SHORT, for the value type parameter (second Tparm).
