175 ;;Quote: ITT 1240 software consists of 200 types of FMMs exchanging messages, either directly or through a digital switching network
175 ;;Quote: the applicable messages for a finite message machine depends on the current state
175 ;;Quote: the message that initiates a new process uses the routing table, later messages go directly to the process
176 ;;Quote: since the message handler sees all messages, messages are easily traced for simulation and checking
176 ;;Quote: most ITT 1240 FMMs are assigned to processors independently of the code
177 ;;Quote: ITT 1240 software uses system support machines for frequently-used modules; invoked by procedure call instead of message
178 ;;Quote: for future applications, a message interface includes messages for all relevant information; currently unused messages are ignored
