Your SEND PAGE command also tells BMS how to deliver the pages to the terminal. For display terminals, you want CSPG to send one page at a time, at the request of the terminal operator. For printers, you want to send one page after another. You control this with the AUTOPAGE or NOAUTOPAGE option on your SEND PAGE command. NOAUTOPAGE lets the terminal operator control the display of pages; AUTOPAGE sends the pages in ascending sequence, as quickly as the device can accept them. If you specify neither, BMS determine which is appropriate from the terminal definition.
