  ASK, A Simple Enow ledgeable System, is a total system f o r the structuring, manipulation and communication of information. It is a simple system i n t h e sense t h a t i t s development concentrated on clean engineering solutions t o what could be done now with good response times.

To introduce you to ASK, we will start out v i t h

a fev examples of queries of a simple data base concerning ships. The uninitiated user may wish simply to ask:
