This document contains a product specification including
interface description for the monitor procedure FILL
̲MTCB.
1.1 I̲N̲T̲R̲O̲D̲U̲C̲T̲I̲O̲N̲
This procedure is used by NSS subsystem to extract
header information from messages arriving to the node.
The information extracted is unpacked and placed in
a work area. MON MTCB, WRITE is called to transfer
the data to a real or a pseudo in TCB.
The messages in question are
1) Narrative messages (data is transferred to a real
MTCB)
2) Control messages (data is transferred to a pseudo
MTCB)
3) ACK/NACK messages (data is transferred to a pseudo
MTCB)
When calling the monitor a MTCB must be present and
the header of the message in question must be in memory.
Information to the monitor is delivered in a work area
of 4 words, describing the index of the MTCB to be
filled, the message type, the offset to the binary
header of the message and an offset to a work area
available for the monitor procedure.
When exiting the monitor procedure the MTCB is updated.

MON FILLMTCB
Register use at:
CALL RETURN
6 ref (work-area) ref (work-area)
7 link completion code
Return points:
OK: link + 1
error: link + 0
The completion code is 0, if exit is ok.
Exit in error occurs, when WRITE ̲MTCB returns with
error. See error codes for WRITE ̲MTCB in Data I/F
Ref., table 2-7.
Work area: (4 words)
WORD0: ref. MTCB index
WORD1: Message type (0 = narrative, 1
= control (except ACK/NACK), 2
= ACK/NACK)
WORD2 ref. binary header of message
WORD3 ref. work area of 21 words (13
words for MTCB, WRITE call + 8
words for register save)
3.3 P̲R̲O̲C̲E̲S̲S̲I̲N̲G̲
Fig. 3.1 shows the flow chart of FILL ̲MTCB.
Main events are:
MTCB index, message type, offset to binary header and
offset to work area is read from the input buffer.
The input registers are saved (1). If the message is
of type narrative or control the binary header is read
and data is transferred to the MTCB block in the work
area (2,3)
If the message is of type:
Narrative: The remaining data is copied from
binary header to the MTCB block.
(CLASS, address list offset, info
precedence).
The update code to be used when
calling MTCB, WRITE is set (4)
CONTROL: The update code to be used when
calling MTCB, WRITE is set (5)
ACK/NACK: The binary header of the message
is read and data is transferred
to the pseudo MTCB block in the
work area. The update code to
be used when calling MTCB, WRITE
is set (6).
MTCB, WRITE is called. If error, the registers
are reestablished, the error code is set and the
procedure is exited.
If no errors, the registers are reestablished,
the completion code is set to zero and the procedure
is exited in link 1.

When calling the procedure a work area of 21 words
is delivered. Word 0 - 12 is used to build the pseudo
or real MTCB; read 13 - 20 is used to store registers.

Information is moved from the incore binary header
to the MTCB (using WRITEMTCB) in the following 3 different
ways: (see the following figures)

Command files used at generation of the object code
file can be found in FIXLIB source directory (ref.
III).
Generation of object code file:
o Copy the source directory of the actual version
into a work directory.
o Activate the command file FILL ̲MTCB.CR
o Activate the command file FILL ̲MTCB.CP
o Activate the command file FILL ̲MTCB.L[
The code ready for installation is now available in
the file FILL ̲MTCB.C.
L̲I̲S̲T̲I̲N̲G̲S̲:̲
Compiler verification - and linker printouts may be
obtained by activating the command file FILL ̲MTCB.PP.
