Riassunto

This interactive text/disc package will help the reader to master Turbo Pascal Graphics faster than with a conventional book, a series of lectures or thumbing through thick manuals. Not only will the student learn more using this package, but the teacher needs to do less teaching. It is aimed at the general user of Turbo Pascal who wants to find out rapidly what is available in TP Graphics and who wants to start writing application programmes. Learning is split up into manageable chunks which are interspersed with activities to illustrate the principles covered. Fifteen demonstration programs and solutions to the activities in the text are supplied on a 720kb 3.5 inch MS-DOS disc.
