System option #1 determines the default terminal number for the SEND statement.
If you set option #1, the default terminal number is 255, and the message being sent is inserted into the global message queue. System option #13 also sets the default terminal number, and it overrides option #1. If option #13 is set, option #1 is ignored.
If you don’t set option #1 or #13 and you don’t specify a terminal number in a SEND statement, the default terminal number is the number of the terminal running the program. The message is inserted into the terminal’s local message queue.
For more information about sending and receiving messages, see Synergy DBL messages and message queues and Receiving messages.
