The TRIGGER statement allows the active controller to send a trigger message to a specified IEEE-488 device or to all listen addressed devices on the IEEE-488 bus. You specify either an I/O Path or a device selector that refers to one or more IEEE-488 devices. For example:
ASSIGN @Gpib to 705
TRIGGER @Gpib
If primary device addresses are specified, the bus action is: ATN, UNL, LAG, GET. If only an interface select code is specified, the bus action is: ATN, GET. If the computer is not the active controller, an error is generated.
