87 // unset: In this case (the default) JSBSim would only print
88 // out the normally expected messages, essentially echoing
89 // the config files as they are read. If the environment
90 // variable is not set, debug_lvl is set to 1 internally
91 // 0: This requests JSBSim not to output any messages
93 // 1: This value explicity requests the normal JSBSim
95 // 2: This value asks for a message to be printed out when
96 // a class is instantiated
97 // 4: When this value is set, a message is displayed when a
98 // FGModel object executes its Run() method
99 // 8: When this value is set, various runtime state variables
100 // are printed out periodically
101 // 16: When set various parameters are sanity checked and
102 // a message is printed out when they go out of bounds
