I use it for a CAD system widely used in commercial Jacquard weaving (where the design is woven into the fabric) of upholstery, decorative and apparel fabrics, throws, etc. About 250,000 lines of code of which 96%+ is Pascal, a bit less than 4% assembler for bottleneck procedures. You may be wearing, sitting on, or wrapping yourself in something designed with a Pascal program...
