The reader who is not familiar with ADTs may, after having read up to this point, get the impression that ADTs are quite complex and not easy to use. The specification with ADTs is a matter of getting used to it. The advantages result from the philosophy behind ADTs.

The use of ADTs becomes a little bit easier with the existence of predefined types. SDL offers a number of them which are supposed to be of general use:

Boolean
Character
Charstring
Integer
Natural
Real
PId
Duration
Time

Furthermore, there are some predefined generators:

String
Array
Powerset
