Specifying a session parameter
A BIND request and response contain parameters that specify
certain protocols used by the PLU and SLU for the session. This appendix
describes the format of the session parameter as seen by a VTAM® application program. The macroinstructions
used to establish a session and specify session parameters are described
in Establishing parameters for sessions. For a detailed description
of the session parameters themselves and how to use them, see:
- Establishing and terminating sessions with logical units, as well as the
- SNA Format and Protocol Reference Manual: Architectural Logic, SNA Formats, SNA Sessions between Logical Units, and
- SNA Concepts and Products
VTAM supplies a default logon mode table containing examples of session parameters for certain devices. This table is described in detail in the z/OS Communications Server: SNA Resource Definition Reference.
Note: This appendix describes fields applicable to session
parameters and is not to be used to locate fields in an SNA BIND request.
Because the SNA BIND request is created by VTAM and not the application program, the BIND
request contains fields set by VTAM that
have no significance to the application program. Also, corresponding
fields in the session parameters and the BIND request can have different
formats and be located in different positions.
