A-Shell/Windows supports saving information to, and retrieving it from the Registry. See MX_REGISTRY for full details.

Although direct access to the Registry is not available for applications running A-Shell/UNIX, Steve Evans of Madics has developed a pair of routines (INIX.SBX and SYSREG.SBX) which allow information to be saved using a similar model but which work on all platforms. See the routines in the A-Shell Source Library for details.
