Announcing A D A - T U T R The Interactive Ada Tutor! Software Innovations Technology proudly announces Version 3 of ADA-TUTR, an interactive tutorial that trains people to be excellent Ada programmers in minimum time. Version 3 includes the latest Ada 9X material. When run on an IBM-compatible PC, ADA-TUTR requires no Ada compiler. A list of Ada compilers available for the PC is included, however. Because the Ada source code is supplied with the program, ADA-TUTR also runs on other computers with Ada compilers, such as mainframes and workstations. 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). The Defense Appropriations Act of 1991 extends this mandate to all defense applications software. 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. Individuals, schools, and companies may try ADA-TUTR without charge (except for a copying fee). To use ADA-TUTR after a free trial, an individual registers for a one-time charge of only $25. Organizations buy licenses for a one-time charge as follows: Number of Users: Price of License: Up to 100 only $450 A license may always be Up to 500 only $725 upgraded for only the Up to 2000 only $950 difference in price. Unlimited only $2400 Individuals can earn generous commissions by distributing copies of ADA-TUTR. Full information is included with the program. Updates of ADA-TUTR are issued periodically. Registered and licensed users receive updates on a 5.25" disk for only $5, or on a 3.5" disk for only $10. Send only $10 for a trial copy of ADA-TUTR on a 5.25" disk, or send $30 for a registered copy for full use by one individual, with one year of Technical Support. Send $5 more if you prefer a 3.5" disk. Software Innovations Technology 1083 Mandarin Dr. NE, Palm Bay, FL 32905-4706 (407)951-0233
