Initiating sessions for SNA terminals

When INIT=SEC is coded in the network definition for a simulated SNA terminal, the terminal sends an INIT-SELF command to the system under test requesting a session with an application named in the RESOURCE operand of the definition. You can also initiate the session by coding a CMND statement that generates a formatted INIT-SELF command. The following message generation deck causes a terminal to generate an INIT-SELF command that contains a resource name of RES and a logon mode table entry name of BATCH. The terminal does not continue in message generation until the terminal receives an SDT command.

LOGINIT MSGTXT
        CMND   COMMAND=INIT,RESOURCE=RES,MODE=BATCH
        ENDTXT

If your test system processes unformatted system services (USS) requests, you can code a SYSREQ statement followed by a TEXT statement containing a logon message for the SLU. In the following example, the DELAY statement causes different start delays when multiple terminals reference the message generation deck to generate their logon messages. The SYSREQ statement places the terminal in the SSCP-LU session state. The TEXT statement generates the logon message. The WAIT statement stops message generation and sets the WAIT indicator for the terminal. The logon message is transmitted and the terminal WAIT indicator remains set until the terminal receives a BIND command.

LOGON     MSGTXT
          DELAY  TIME=A20
0         IF     LOC=RU+0,TEXT=(ANYTHING),
                 ELSE=B-NOSYSREQ
          SYSREQ
NOSYSREQ  TEXT   (LOGON APPLID((TSO)) USER(($ID,8$/PASSWORD)))
          WAIT
          ENDTXT
