QuickPascal

Extracted from the Wikipedia article Microsoft Pascal.
Overview
Unlike the ISO-compliant Microsoft Pascal product, QuickPascal was compatibile 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.
