Back Home Up

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:

bulletBoolean
bulletCharacter
bulletCharstring
bulletInteger
bulletNatural
bulletReal
bulletPId
bulletDuration
bulletTime

Furthermore, there are some predefined generators:

bulletString
bulletArray
bulletPowerset
