Arden Syntax v2.10 | Arden Syntax 3.0 Proposal

Rule sets, called Medical Logic Modules, comprise enough logic to make a single medical decision. Medical logic modules are written in Arden syntax, and are called by a program – an event monitor – when the condition they are written to help with occurs.
