SET PROGRAM
ECHO { ON | OFF | CURRENT }
overrides the terminal echo mode (that is, the mode configured for a terminal at
system generation time) so that character input appears correctly on the
terminal. The ECHO attribute supports terminals running in conversational or
intelligent mode.
If you omit this attribute, the default is ON.
EXCLUSIVE { ON | OFF }
specifies whether a TCP should open a terminal for exclusive or shared access.
If you omit this attribute, the default is OFF.
IOPROTOCOL { 0 | 1 }
specifies the protocol the TCP follows when a SCREEN COBOL SEND
MESSAGE statement completes with a timeout or an unsolicited message.
If you omit this attribute, the default is 0.
ON Directs input to appear on the terminal screen.
OFF Corrects the display by suppressing the duplicate characters (if a
terminal is configured so that it displays input characters). If you
define this option for the supported terminal types T16-6520,
T16-6530, and T16-6540, no input characters appear on the
terminal screen.
CURRENT Directs the TCP to obtain the operating mode of the terminal
from the operating system and to use that mode when it opens the
terminal. If you specify this option for a process that is running
as a terminal emulator, this attribute value defaults to ON.
ON Directs a TCP to open the terminal for exclusive access. The TCP
cannot allow simultaneous access of any kind to the terminal by
any other process.
OFF Directs a TCP to open the terminal for shared access. The TCP
allows simultaneous read and/or write access to the terminal by
other processes.
0 Directs a TCP to issue a CANCEL procedure to cancel a SEND
MESSAGE I/O. The I/O is cancelled because an unsolicited message
arrives or a SEND MESSAGE TIMEOUT occurs.
1 Directs a TCP to use a CONTROL-26 protocol to cancel a SEND
MESSAGE I/O. The I/O is cancelled because an unsolicited message
arrives or a SEND MESSAGE TIMEOUT occurs. Front-end processes
can use this attribute to avoid loss of data.
