When only part of the message data could be received, IUCV sets this
bit to 1 as output from the RECEIVE function. IUCV sets this bit so
that the resulting parameter list is valid input to a subsequent
RECEIVE. IPFGPID (X'02') (Input to PURGE, RECEIVE, REJECT, TESTCMPL) (Output from DESCRIBE, RECEIVE)
As an input, this bit indicates that a path ID has been specified in field IPPATHID. This bit is set by the IUCV macro when the PATHID= parameter is specified on the macro.
IUCV sets this bit to 1 as output from the DESCRIBE function so the
resulting parameter list is valid input to the next function (normally
RECEIVE OR REJECT).
IUCV sets this bit to 1 as output from the RECEIVE function when
only part of the message data could be received. IUCV sets this bit so
that the resulting parameter list is valid input to a subsequent
RECEIVE. IPFGMID (X'04') (Input to PURGE, RECEIVE, REJECT, TESTCMPL) (Output from DESCRIBE, RECEIVE)
As an input, this bit indicates that a message id has been specified in
field IPMSGID. This bit is set by the IUCV macro when the MSGID= parameter is specified on the macro. IUCV sets this bit to 1 as output from the DESCRIBE function so the
resulting parameter list is valid input to the next function (normally
RECEIVE or REJECT).
When only part of the message data could be received, IUCV sets this
bit to 1 as output from the RECEIVE function. IUCV sets this bit so
that the resulting parameter list is valid input to a subsequent
RECEIVE. IPNORPY (X' 10') (Input to SEND) (Output from DESCRIBE, PURGE, RECEIVE)
(Reflected in the pending-message IUCV external interrupt.)
As an input, this bit indicates, when set to one, that this is a one-way
transaction. When the target invokes the RECEIVE function for this
message, IUCV queues the MSGBLOK representing this message on
the source communicator's reply queue. No reply by the target is
Inter-User Communications Vehicle 165
IPPRTY allowed. If this bit is zero, it indicates a two-way transaction. The
message is queued on the source's reply queue only when the target
invokes the REPLY function for this message.
As an output or on an external interrupt, this bit indicates, when set to
one, that this message does not take a reply.
(X'20')
(Input to ACCEPT, CONNECT, REPLY, SEND) (Output from DESCRIBE, PURGE, RECEIVE, TESTCMPL)
(Reflected in these IUCV external interrupts: pending connection,
pending message, message complete.)
As an input to CONNECT, this bit indicates, when set to one, that the
source wishes to establish a path that can handle priority communi­
cations. When invoked from a virtual machine, priority must also be
authorized in the IUCV directory control statement. When invoked
from CP system code, this bit is always set to one.
As an input to SEND and REPLY, this bit indicates, when set to one,
that this message or reply, is a priority message or reply. If this path
was established to handle priority communications, the message is
handled as a priority message. If the path cannot handle priority mes­
sages, IUCV generates a nonzero return code.
As an output or on an external interrupt for pending message or mes­
sage complete, this bit indicates that the message is a priority message. IPQUSCE (X'40') IPALL 166 VM/SP System Programmer's Guide
(Input to ACCEPT, CONNECT)
(Reflected in these IUCV external interrupts: pending connection,
connection complete.)
As an input, this bit indicates, when set to one, that the communicator
wishes to establish a quiesced path. The other communicator is not
able to send messages on a quiesced path. The path can be restored to
full communication capability by invoking the RESUME function. On an external interrupt, this bit indicates, when set to one, that the
path is quiesced. The path must be resumed by the communicating
partner before messages can be initiated by this user.
(X'80')
(Input to QUIESCE, RESUME, SEVER)
When this bit is 1, IUCV performs the specified function on all paths
for this virtual machine.
If this bit is specified, IUCV ignores the IPP ATHID field. ,/0-
