m Figure 5. RKRL micro-worlds. Contains, the model, is defined in terms of a <domain> (the micro-world of sets), a <range>, a <test> for member- ship, and a <process> for finding members in a local context. The first frame says that Contains has a <process> called SetA ccumulate. The fourth line says that Contains is defined over sets (which is a complete micro-world). The items in <brackets> are defined in the meta micro-world. The <test> process consists of a chunk of Excel Visual Basic for A pplica- tions (VBA) macro language that will test a frame with a stan- dard binding (modelVar is bound to the model part of the frame). These string models tell the RKRL interpreter (embryonic at present) how to use chunks of code to construct programs that create and manipulate objects, perform model- based reasoning, and otherwise control the software radio platform.
