Overview

Microsoft Pascal version 1.0 was released in 1980. The last version of Microsoft Pascal to be released was version 4.0 in 1988, when Microsoft Pascal was superseded by Microsoft QuickPascal, a cheaper development tool that Microsoft produced in order to compete with Borland's Turbo Pascal. Microsoft Pascal was priced at , whereas QuickPascal was priced between , and the differences between the two were similar to those between Microsoft BASIC Professional Development System and Microsoft

. Unlike the ISO-compliant Microsoft Pascal product, QuickPascal went after the ultimate compatibility with Turbo Pascal. This included not only source-level compatibility, but rather complete binary compatibility with widely available unit libraries for the competitor's compiler. To achieve this level of compatibility, QuickPascal moved away from the common file format (OBJ) and tool set (LINK, LIB) shared by Microsoft's other compilers.
