Lesson plan

Apple Pascal

Apple Pascal is an implementation of Pascal for the Apple II and Apple III computer series, based on UCSD Pascal. Just like other UCSD Pascal implementations, it runs on its own operating system (Apple Pascal Operating System, a derivative of UCSD p-System with graphical extensions). Originally released for the Apple II in August 1979, just after Apple DOS 3.2, Apple Pascal pioneered features that were incorporated into DOS 3.3, as well as others that would not be seen again until the introduction of ProDOS. The Apple Pascal software package also included disk maintenance utilities, and an assembler meant to complement Apple's built-in "monitor" assembler. A FORTRAN compiler (written by Silicon Valley Software of Sunnyvale, California) compiling to the same p-code as Pascal was also available.
