Standard SNAX/HLS Definitions
Common Definitions

ZAPPLNAME
specifies the PLU name carried in the BIND. If the LU is type PLU, then the PLU
name sent in the BIND is the name in the APPLICATION–NAME field of the
OPEN–SESSION or HLS–OPEN verb. If this field is empty, then the PLU–NAME
in the BIND record in the RDT table is used.
If the LU type is PLU, the open mode is ACCEPT, the APPLICATION–NAME
field in the open verb is empty, and there is no PLU–NAME in the BIND record in
the RDT table, then the DLU name in the INIT–SELF is sent as the PLU name in
the BIND.
ZBIND–QUEUING
specifies whether the BIND request can be queued by the secondary LU (SLU). A
value of ZSPI–VAL–TRUE means the SLU can queue the request; a value of ZSPI–
VAL–FALSE means the SLU should respond to the BIND request immediately.
This value is set by the BIND message and is meaningless before the BIND
message flows. SNAX/HLS does not currently process or interpret this value.
ZBIS–SENT
indicates whether the previous instance of this session sent a BIS request. This
value is used only for LU session type 6.1. This value is set by the BIND message
and is meaningless before the BIND message flows. SNAX/HLS does not
currently process or interpret this value.
ZBRKT–RESET
indicates how the bracket state manager behaves as a result of a reset signal. This
value is set by the BIND message and is meaningless before the BIND message
flows.
SNA brackets are used to demarcate logical units of work. They are often used in
half–duplex send/receive modes. They may be required if certain recovery
features are required from the IBM device or product. The typical setting for a
3270 LU type 2, for example, is ZHLS–VAL–BRKT–RESET–BETB, indicating that
brackets are used and the reset state is between brackets (BETB).
This field has the following enumerated values:
ZHLS–VAL–BRKT–RESET–BETB
states that the reset state for brackets is BETB.
ZHLS–VAL–BRKT–RESET–INB
states that either brackets are not used, or they are placed in the in–brackets
state after a reset.
