DAAD System Reference

DAAD (Disenador de Aventuras AD) is a multi-platform text adventure authoring system created by Tim Gilberts in 1988 for the Spanish company Aventuras AD. It evolved from The Quill -> PAW -> SWAN -> DAAD. Adventures are written in DSF source files, compiled to DDB binary databases by DRC, and executed by platform-specific interpreters.

Supported platforms: ZX Spectrum, Amstrad CPC, C64, MSX, MSX2, PCW, Atari ST, Amiga, PC (DOS).
