Release Date: 1/1/1987
Manufacturer: Borland
Turbo Basic is a BASIC compiler and dialect originally created by Robert "Bob" Zale and bought from him by Borland. When Borland decided to stop publishing it, Zale bought it back from them, renamed it to PowerBASIC and set up PowerBASIC Inc. to continue support and development of it.

This software is from the 1987-1988 period and features the Borland "black screen" similar to Turbo Pascal 4.0, Turbo C 1.0/1.5, and Turbo Prolog 1.1. Borland did not adopt its trademark "blue screen" integrated development environment until the 1989 period when Turbo C 2.0, Turbo C++ 1.1, etc. were released. By this time, Turbo Basic and Turbo Prolog were no longer being sold.

Unlike most BASIC implementations of this period, Turbo Basic was a full compiler which generated native code for MS-DOS. Other implementations were either interpreters, or relied heavily on a runtime library. The integrated development environment could run a BASIC program internally for traditional BASIC debugging (see sample below), or generate an MS-DOS stand-alone executable file that could be run on other systems without the Turbo Basic product or runtime libraries.
