4.2.1.7 S̲u̲b̲p̲a̲c̲k̲a̲g̲e̲ ̲I̲n̲t̲e̲r̲f̲a̲c̲e̲
TBD.
4.2.2 P̲r̲i̲n̲t̲e̲r̲ ̲O̲u̲t̲p̲u̲t̲ ̲S̲u̲b̲p̲a̲c̲k̲a̲g̲e̲
The P̲rinter O̲utp̲ut (PROP) coroutine is performing the
actions in connection with formatting and output of
the test to be printed.
PROP is controlled by the other coroutine (UPCO).
4.2.2.1 F̲u̲n̲c̲t̲i̲o̲n̲a̲l̲ ̲S̲p̲e̲c̲i̲f̲i̲c̲a̲t̲i̲o̲n̲
The following functions are performed by this subpackage
(ref. fig. 4.2.2-1):
UPCO Control Functions
Command Completion and Error Report functions
Format Control
Printout
Fig. 4.2.2-1
4.2.2.1.1 U̲P̲C̲O̲ ̲C̲o̲m̲m̲a̲n̲d̲ ̲E̲x̲e̲c̲u̲t̲i̲o̲n̲ ̲(̲1̲.̲0̲)̲
The UPCO Command Execution functions carry out execution
of the command issued by UPCO.
a) I̲n̲i̲t̲i̲a̲l̲i̲z̲e̲ ̲(̲1̲.̲1̲)̲
The Initialize command is issued for initialization
of PROP's working area, i.e. variables and buffers.
A CC-Report is to be sent to UPCO, ref. sec. 4.2.2.1.2.c.
b) C̲o̲m̲m̲e̲n̲c̲e̲ ̲(̲1̲.̲2̲)̲
Upon receipt of a Commence-CMD, PROP will start
printing the current item.
c) A̲b̲a̲n̲d̲o̲n̲ ̲(̲1̲.̲3̲)̲
The Abandon ̲Print Command will cause the printing
actions to be stopped immediately. All outstanding
I/O requests will be cancelled and the working
area will be cleared.
Completion will be reported to UPCO, ref. sec.
4.2.2.1.2.c.
d) C̲o̲n̲t̲i̲n̲u̲e̲ ̲(̲1̲.̲4̲)̲
The Continue Command causes the printout of the
current item to be continued from a well-defined
point. It is used when the printing actions have
earlier been stopped because of paper out on the
printer.
e) R̲e̲s̲t̲a̲r̲t̲ ̲(̲1̲.̲5̲)̲
The Restart Command will restart printing of a
preempted item from a well-defined point.
f) P̲r̲e̲e̲m̲p̲t̲ ̲(̲1̲.̲6̲)̲
Printout of the current item will be stopped and
status will be stored for later restart. Completion
will be reported to UPCO, ref. sec. 4.2.2.1.2.c.
4.2.2.1.2 C̲o̲m̲m̲a̲n̲d̲ ̲C̲o̲m̲p̲l̲e̲t̲i̲o̲n̲ ̲a̲n̲d̲ ̲E̲r̲r̲o̲r̲ ̲R̲e̲p̲o̲r̲t̲ ̲F̲u̲n̲c̲t̲i̲o̲n̲s̲ ̲(̲2̲.̲0̲)̲
These functions handle the receiption and sending of
completion and error reports.
a) P̲r̲o̲c̲e̲s̲s̲i̲n̲g̲ ̲o̲f̲ ̲I̲O̲C̲ ̲C̲o̲m̲p̲l̲e̲t̲i̲o̲n̲ ̲C̲o̲d̲e̲s̲ ̲(̲2̲.̲1̲)̲
When printout data is sent to IOC in a buffer,
IOC will respond with a Completion Code. The Completion
Code will contain information about eventual printer
errors.
b) S̲e̲n̲d̲ ̲E̲r̲r̲o̲r̲ ̲R̲e̲p̲o̲r̲t̲ ̲t̲o̲ ̲U̲P̲C̲O̲ ̲(̲2̲.̲2̲)̲
Upon detection of an error, a report will be sent
to UPCO.
c) S̲e̲n̲d̲ ̲C̲o̲m̲m̲a̲n̲d̲ ̲C̲o̲m̲p̲l̲e̲t̲i̲o̲n̲ ̲R̲e̲p̲o̲r̲t̲ ̲t̲o̲ ̲U̲P̲C̲O̲ ̲(̲2̲.̲3̲)̲
Completion of some of the UPCO commands is to be
reported back, ref. sec. 4.2.2.1.1.a,c,f.
d) S̲e̲n̲d̲ ̲P̲r̲i̲n̲t̲ ̲C̲o̲m̲p̲l̲e̲t̲e̲ ̲R̲e̲p̲o̲r̲t̲ ̲t̲o̲ ̲U̲P̲C̲O̲ ̲(̲2̲.̲4̲)̲
On completion of item printout, UPCO will be notified.
4.2.2.1.3 F̲o̲r̲m̲a̲t̲ ̲C̲o̲n̲t̲r̲o̲l̲ ̲(̲3̲.̲0̲)̲
The Format Control functions are taking care of access
to and input from the P̲rint F̲ormat F̲ile.
a) D̲e̲t̲e̲r̲m̲i̲n̲e̲ ̲F̲o̲r̲m̲a̲t̲ ̲A̲d̲d̲r̲e̲s̲s̲ ̲i̲n̲ ̲P̲F̲F̲ ̲(̲3̲.̲1̲)̲
The Format Descriptor Records pertinent to each
format are stored sequentially in the PFF. This
function determines the start address of the current
format from the PFF-Directory.
b) T̲r̲a̲n̲s̲f̲e̲r̲ ̲D̲a̲t̲a̲ ̲F̲r̲o̲m̲ ̲P̲F̲F̲ ̲t̲o̲ ̲F̲D̲B̲ ̲(̲3̲.̲2̲)̲
Before being processed, the Format Descriptor Records
must be transferred to the F̲ormat D̲escriptor B̲uffer
(FDB), which is a part of PROP's working area.
4.2.2.1.4 P̲r̲i̲n̲t̲o̲u̲t̲ ̲(̲4̲.̲0̲)̲
The printout functions carries out the actual Text-conversion
, -formatting and -output.
a) I̲n̲p̲u̲t̲ ̲D̲a̲t̲a̲ ̲F̲r̲o̲m̲ ̲C̲I̲F̲ ̲(̲4̲.̲1̲)̲
If the current item is stored in a CIF, this function
will take care of transferring data from the CIF
to the Source Buffer.
b) T̲r̲a̲n̲s̲f̲e̲r̲ ̲D̲a̲t̲a̲ ̲F̲r̲o̲m̲ ̲I̲t̲e̲m̲ ̲B̲u̲f̲f̲e̲r̲ ̲(̲4̲.̲2̲)̲
If the current item is contained in a buffer, this
function transfers the data to PRIS's Source Buffer.
c) C̲o̲n̲v̲e̲r̲t̲ ̲D̲a̲t̲a̲ ̲F̲o̲r̲ ̲O̲u̲t̲p̲u̲t̲ ̲(̲4̲.̲3̲)̲
This function is responsible for converting the
data in the FDR and the Source Buffer so that it
can be printed.
d) L̲o̲a̲d̲ ̲C̲o̲n̲v̲e̲r̲t̲e̲d̲ ̲D̲a̲t̲a̲ ̲I̲n̲t̲o̲ ̲O̲u̲t̲p̲u̲t̲ ̲B̲u̲f̲f̲e̲r̲ ̲(̲4̲.̲4̲)̲
When the data has been converted (ref. sec. 4.2.2.1.4-c),
this function loads it into a buffer for Output.
e) L̲o̲a̲d̲ ̲H̲e̲a̲d̲e̲r̲/̲T̲r̲a̲i̲l̲e̲r̲ ̲I̲n̲f̲o̲.̲ ̲I̲n̲t̲o̲ ̲O̲u̲t̲p̲u̲t̲ ̲B̲u̲f̲f̲e̲r̲ ̲(̲4̲.̲5̲)̲
The Page Header/Trailer information, which is produced
by UPCO and updated by UPCO and PROP, is appended
to the Output Buffer.
f) O̲u̲t̲p̲u̲t̲ ̲B̲u̲f̲f̲e̲r̲ ̲(̲4̲.̲6̲)̲
This function sends the Output buffer to IOC for
output.
g) P̲a̲g̲e̲/̲L̲i̲n̲e̲ ̲C̲o̲n̲t̲r̲o̲l̲ ̲(̲4̲.̲7̲)̲
Page and Line control keeps account of the number
of printed lines on each page and provides page
shift actions when appropriate.
4.2.2.2 S̲o̲f̲t̲w̲a̲r̲e̲ ̲S̲t̲r̲u̲c̲t̲u̲r̲e̲
Two kinds of items can be sent to semaphore S2 and
thus invoke PROP.
a) The UPCO Commands, which are used by UPCO to Control
PROP.
b) The IOC Completion Codes, which are used by PROP
to synchronize and control its printout actions.
The software structure is depicted in fig. 4.2.2.2-1.
The description of each component is very similar to
the one in the functional specification (sec. 4.2.2.1),
and thus it shall not be repeated here.
