SNAX/HLS Management Programming Manual

Standard SNAX/HLS Definitions
Common Definitions

ZHLS–VAL–FSM–CHDX–RSP–NEG–SEEN
indicates that a negative response to the current chain is being processed and
the send state manager or receive state manager is being called with the
negative response as input. This value should never be visible to requesters; it
is an internal state only.
ZHLS–VAL–FSM–CHDX–RSP–NULL
indicates that this FSM is not yet initialized or is not used in the current
session.
ZHLS–VAL–FSM–CHDX–RSP–RESET
indicates that no user message (SNA chain) is in progress.
ZFSM–EBCD
reports the SNAX/HLS implementation of FSM_EBCD. This FSM enforces a
check that prevents processing a message that carries end–brackets
(END–TRANSACTION–IND = Y) from having the change direction indicator set
(PREPARE–TO–RECEIVE = YES) at end of chain. In other words, at the end of a
chain that ends a transaction, the CDI (change direction indicator) cannot be set.
Such a request violates SNA protocol.
This field can have one of the following enumerated values:
ZHLS–VAL–FSM–EBCD–INC
specifies that a chain is being processed.
ZHLS–VAL–FSM–EBCD–NULL
indicates that this FSM is not yet initialized or is not used in the current
session.
ZHLS–VAL–FSM–EBCD–RESET
specifies that no chain is currently being processed.
ZFSM–IMM–RQ
reports the SNAX/HLS implementation of FSM_IMM_RQ_MODE. This FSM
enforces the immediate request protocol. In this mode, there can be only one
request outstanding that is awaiting a definite response.
This field can have the following enumerated values:
ZHLS–VAL–FSM–IMM–RQ–DR–CNCL
indicates that a CANCEL request has arrived.
