Message Transmitting Function
After you have filled all character positions on the screen, send the displayed informa-
tion to the CPU before continuing data entry. When a data character is entered in the
next-to-last character position on the screen, the audible alarm sounds to remind you
that the cursor is near the end of the screen. If you continue to enter data, the cursor
“wraps” and reappears in the first available character position of the screen. Subse-
quently entered characters replace displayed characters, resulting in loss of previous
entries.
After filling all required character positions on the screen, press the Enter key to request
a communications line for sending displayed data to the CPU.
Press the Clear key to erase all displayed data on the screen, return the cursor to the first
available character position, and signal the CPU that a “clear” operation has occurred.
The application program in use determines specific functions of the Program Access
(PA) and Program Function (PF or F) keys. Contact your supervisor or refer to a system
user’s guide for further information regarding these keys.
Press a Program Access key to initiate a program-determined function. Program Access
keys are designated by numbers PA1, PA2, and PA3.
Press a Program Function key to initiate a program-determined function. Program
Function keys are designated by numbers PF1 or F1 through PF24 or F24.
As described in “Assigning a Coax Printer” on Page 4-2, you can assign a printer in the
system configuration that generates copies of information displayed on the screen. The
following procedure explains how to initiate a print operation on a coax printer.
After entering data on the screen, press the Print key to send data to the assigned coax
printer for generating copy.
Press the Alt and Reset keys to cancel a pending request by the Print key and restore
keyboard operation. If the assigned printer is not operating, press the Alt and Reset keys
to restore keyboard operation and reset the
condition symbol.
The display station also can be used to send system request messages to the CPU,
depending on the online rules condition symbol that appears in the operator status row.
