CLOCK PORT
The CLOCK PORT instruction first searches the environment table for an entry 'PLB_PORT=xxx' that defines your current port or workstation number. If not found, the operating system or network standard is utilized to retrieve the port number.
Refer to Multi-User Support information for specific information regarding CLOCK PORT under multiple usage applications. The PORT information not only returns the current port ID but the terminal characteristics that follow:
