Abstract

This article describes a DOS interrupt service routine which provides rapid low-level graphics capabilities from a high-level interface. By implementing low-level assembly language functions in a DOS interrupt service routine (ISR), high-level language programmers can have extensive graphics capability. The result is a simple high-level language interface combined with the speed of an assembly language routine.
