Learning Level 11 -- David A. Lien (Compusoft Publishing, San Diego, Calif., 1979, 352 pp., $15.95)

This instruction text for the Radio Shack Level 11 Basic language is written in the same easy-to- digest, step-by- step style es lien's User'sManualforLevell, which accompanies each Radio Shack computer. Since the original manual is apt to be the TRS-80 user's first introduction to the use of a computer, Lien has included a "cut and paste" appendix to Learning

Level 1I so that the beginner can use the introductory text as a guide to a Level 11 system with the appropriate material altered. This is certainly a diligent attempt to adapt the original support material to Level 11 equipment.

Besides giving elementary explanations of the major capabilities of the Level 11 language, the book provides sections on converting Level I programs to run on Level 11 equipment, the use of the expansion interface, and dual cassette operation. The appendix on error messages is especially instructive for the beginner. Providing test programs that generate error messages, Lien then carefully explains the error sources.

Although there are a fair number of typographical errors, none should cause the user much trouble. However, one program does not do what Lien leads his reader to expect: The instring routine on pages 162-166 will not find strings buried too deeply within other strings. (The offending program line is 1000.) However, the user who discovers this will learn some program debugging techniques as he sets things straight.

This text will serve a useful role for the computer hobbyist. Soon, texts of this type will demystify the simple use of computers for thousands of nontechnical users.
