SysMLv1: A basic ControlFlow, ObjectFlow, and DecisionNode loop driven by fUML ReadLine CLI String input with conversion to Boolean for LiteralBoolean guard [with mini video]

A convenient way to explore a DecisionNode in Magic Model Analyst^® (Cameo Simulation Toolkit^®) is to use the ReadLine Activity from the fUML_Library.mdzip, which you can load via Use Project > Use Local Project then select under <install.root>/modelLibraries. You can then input 'test' values via a CLI in the simulation console.

In this example, rather than using Cameo's "magical" implied variable detection based on a "freestyle" guard, the input is converted to a hard Boolean true or false so that a LiteralBoolean can be used on the guard [true].

This version does not use an explicit «decisionInputFlow», so it does not need an "extra" ControlFlow to the DecisionNode:
