ZIOPROTOCOL

specifies the protocol the TCP follows when a SCREEN COBOL SEND MESSAGE
statement completes with a timeout or unsolicited message. ZIOPROTOCOL can
have the following values:
Directs the TCP to issue a Guardian CANCEL procedure to cancel a SEND
0
MESSAGE I/O operation. The I/O operation is cancelled because an
unsolicited message arrives or a SEND MESSAGE TIMEOUT occurred.
Directs the TCP to use a Guardian CONTROL-26 protocol to cancel a SEND
1
MESSAGE I/O operation. The I/O operation is cancelled because an
unsolicited message arrives or a SEND MESSAGE TIMEOUT occurred.
If you specify a value of 1 for ZIOPROTOCOL, the front-end process must be
written according to rules specified in the TS/MP Pathsend and Server
Programming Manual. Front-end processes can use this setting to avoid loss of
data.
If you do not assign a value to this field, the default is 0.

ZMAXINPUTMSGS

specifies the maximum number of unsolicited messages that the TCP queues for a
specific TERM object. If this number is exceeded, the TCP returns a
TERM^QUEUE^FULL error to the originator of the unsolicited message. The value
can be from 0 through 2045.
If you do not assign a value to this parameter, the default is 0.

ZTCLPROG

is the name of the SCREEN COBOL object library file that the TCP uses to locate
the screen programs for its TERM objects. If you specify a TCLPROG file name in
either an ADD TERM or ADD PROGTERM command, the TCP first checks that file
for the requested program unit and then checks the TCLPROG file in
ZPWY-DDL-DEF-TCP.
You can specify either a specific node name or \*, a generic name representing the
node on which the PATHMON process is currently running. If you do not specify a
node name, the default node for file-name expansion can be affected by the value
you specify for the ZNODEINDEPENDENT field of the TS/MP START PATHWAY
command. For more information on node independence, see the Pathway/iTS
System Management Manual.
When, in response to a SCREEN COBOL CALL statement, the TCP cannot find a
program unit in the TCLPROG file defined for a PROGTERM, but finds it in the
TCLPROG file defined for a TCP, the TCP records where the program unit was
located. However, until the TCP is able to locate the program unit in the TCP
TCLPROG, the TCP continues to look for it in the PROGTERM TCLPROG file on
each call. This behavior can result in high processing overhead.
