ADA-TUTR by Software Innovations Technology Registration($25.00) Software Innovations Technology proudly announces ADA-TUTR, an Ada Tutor program to train people to be excellent Ada programmers in minimum time. It runs on PCs as well as mainframes. Ada is an ideal programming language, because Ada programs tend to have fewer errors, to be easier to read, and to be much easier to modify later. The U.S. Department of Defense mandated the use of Ada in mission-critical systems (DoD Directive 3405.2, 1987). Not just a "quiz," ADA-TUTR is a thorough course of interactive instruction that even checks "homework" assignments. ADA-TUTR teaches good program design, not just syntax, so that programs will take advantage of the features of Ada that make them more reliable and easier to maintain. ADA-TUTR was written by John J. Herro, Ph.D., who taught graduate courses in Ada at the Florida Institute of Technology and the State University of New York. He also taught Ada to employees of General Electric Co., Grumman Aerospace Corp., and Harris Corp. When ADA-TUTR is run on a PC, an Ada compiler is helpful, but not required. A list of Ada compilers available for the PC, some of them inexpensive, is included. The PC needs a hard disk, and can have a monochrome or color monitor. Since ADA-TUTR comes with Ada source code, it will run on other computers with Ada compilers.
