TheAtari Pascal Language System (usually shortened toAtari Pascal) is a version of thePascal programming language released byAtari, Inc. for theAtari 8-bit computers[1] in March 1982.[2] Atari Pascal was published through theAtari Program Exchange as unsupported software instead of in Atari's official product line.[3] It requires two disk drives, which greatly limited its potential audience. It includes a 161-page manual.[2]
Atari Pascal was developed by MT Microsystems, which was owned byDigital Research. It's similar to MT/PASCAL+ from the same company.[3] Thecompiler produces code for avirtual machine, as withUCSD Pascal, instead of generatingmachine code, but the resulting programs are as much as seven times faster thanApple Pascal.[3] MT Microsystems wrote Atari Pascal with a planned "super Atari" 8-bit model in mind, one with 128K of RAM and dual-floppy drives (similar to a common configuration of the 1983Apple IIe).[3] This machine never materialized, but the software was released because of pressure within Atari, though only through the Atari Program Exchange.
Atari's 1980 in-store demonstration program mentions Pascal as one of the available programming languages, despite Atari Pascal not being released until 1982.
Draper Pascal for the Atari 8-bit computers was released in 1983,[4] Kyan Pascal in 1986,[5] and CLSN Pascal in 1989.[6] Each works with a single floppy drive, a point emphasized in Draper Pascal magazine ads.
