Description: Turbo Pascal is a software development system that includes a compiler and an integrated development environment (IDE) for the Pascal programming language running on CP/M, CP/M-86, and DOS. It was originally developed by Anders Hejlsberg at Borland, and was notable for its extremely fast compiling times. Turbo Pascal, and the later but similar Turbo C, made Borland a leader in PC-based development.
