4.2.5.2 S̲o̲f̲t̲w̲a̲r̲e̲ ̲S̲t̲r̲u̲c̲t̲u̲r̲e̲
The UFCO subpackage consists of one coroutine with
semaphore S2 as the main waiting point.
The input from S2 will be a command which is received
from VCO, VDIA, RETR, the answer queue or the VDU.
Each command will consititute a main function and is
implemented as a procedure (ref. figure 4.2.5.2-1).
Furthermore, some common functions exist which are
called by the main function.
Figure 4.2.5.2-1 UFCO Software Structure
4.2.5.2.1 V̲C̲O̲ ̲C̲o̲m̲m̲a̲n̲d̲
a) Initialization (141)
Performs the initialization of local memory. In
case of recovery, the contents of the answer queue
are sent to the corresponding PREP queue.
b) User On (142)
Reads the validation table corresponding to the
capability of the user.
Displays the corresponding menu.
c) Resume (143)
An init receive function key will be issued.
d) Close Down (144)
Controls all the types of close down (i.e. user
off, blocks terminal and ordered close down).
4.2.5.2.2 F̲u̲n̲c̲t̲i̲o̲n̲ ̲K̲e̲y̲s̲
a) Delete Lines (151)
Sends a delete line command to VDIA
b) Insert Lines (152)
Sends an insert line command to VDIA.
c) Display Error Message (153)
The text associated with an error code is displayed
on the VDU response line.
d) Execute Command (154)
The number of procedure which constitutes the function
of the command is executed.
e) Execute Function Key (155)
The number of procedures which constitute the function
of the function key is executed.
4.2.5.2.3 V̲D̲I̲A̲ ̲C̲o̲m̲m̲a̲n̲d̲s̲
a) VDIA Completion (161)
The numbers of precedences which must be performed
upon reception of a completion code from VDIA are
started.
4.2.5.2.4 R̲E̲T̲R̲ ̲C̲o̲m̲m̲a̲n̲d̲s̲
a) Off-line Notification (171)
A response message is displayed in the response
line. The user menu is displayed.
b) On-line Retrieval (172)
It is checked if the requestor is still signed-on.
The received CIF is either displayed or sent to
the response queue.
c) On-line Append (173)
It is checked if the requestor is still signed-on.
The received CIF is either appended or sent to
the PREP queue.
4.2.5.2.5 A̲n̲s̲w̲e̲r̲ ̲Q̲u̲e̲u̲e̲ ̲M̲o̲n̲i̲t̲o̲r̲i̲n̲g̲
a) Answer Queue Monitoring (181)
The number of procedures to be performed after
reception of a CIF in the answer queue is executed.
b) Receive Acknowledge (182)
Acknowledgements for reception of audit data are
received in the answer queue.
Detected errors will be reported to aVCO.
4.2.5.2.6 C̲o̲m̲m̲o̲n̲ ̲P̲r̲o̲c̲e̲d̲u̲r̲e̲s̲
a) Error Reporting (2.1)
Errors which are due to system faults are reported
to VCO.
b) Display Error Code (2.2)
Errors which are due to user faults will be displayed
in the VDU response line.
c) Start Sequence (2.3)
This is a number of support procedures which will
control the execution of commands received by UFCO.

As a basis for calculations the following figures are
used:
- 31 modules of 150 source statements
- 1 source statement equals 2 bytes
- 2k bytes data buffer per VDU controlled
- 32 VDUs max.
This gives:
Aprox. 5000 source statements = 10 kb
32 x 2 kb = ̲6̲4̲ ̲k̲b̲
Approx 75 kb
