4.2.5.1.1 R̲e̲c̲e̲i̲v̲e̲ ̲a̲n̲d̲ ̲D̲e̲t̲e̲c̲t̲ ̲C̲o̲m̲m̲a̲n̲d̲s̲
The supervisor commands are received and the corresponding
action is activated and a response is awaited except
for the activation of off-load.
4.2.5.1.2 M̲M̲S̲ ̲T̲h̲r̲e̲s̲h̲o̲l̲d̲ ̲W̲a̲r̲n̲i̲n̲g̲
The MMS threshold warning is received from MMS and
the dump procedure is activated.
4.2.5.1.3 D̲u̲m̲p̲ ̲R̲e̲s̲p̲o̲n̲s̲e̲
The asynchronous dump response is received and a dump
completion report is sent to supervisor's report printer
in case of an MMS dump activation. A dump completion
code is returned to supervisor in case of a TEP dump
activation.
4.2.5.1.4 O̲f̲f̲-̲L̲i̲n̲e̲ ̲R̲e̲p̲o̲r̲t̲i̲n̲g̲
The off-line reporting function handles the reception
of mount request report from the off-line retrieval
sub-package. This report tells that the off-line retrieval
sub-package has sent a mount request to the report
printer.
Furthermore, the reporting function performs the catalogue
reporting.
4.2.5.1.5 C̲a̲t̲a̲l̲o̲g̲u̲e̲ ̲T̲h̲r̲e̲s̲h̲o̲l̲d̲ ̲R̲e̲p̲o̲r̲t̲i̲n̲g̲
Exceeding of threshold values for the catalogue is
reported to the supervisor command subpackage. Exceeding
may occur during online storage, offline dump or recovery.
The supervisor command subpackage issues a report to
the supervisor's report printer indicating the actual
catalogue threshold exceeding.
4.2.5.2 S̲o̲f̲t̲w̲a̲r̲e̲ ̲S̲t̲r̲u̲c̲t̲u̲r̲e̲
The software structure consists of one coroutine handling
all functions performed by this sub-package. A number
of modules are identified, refer figure 4.2.5.2-1-3.

Refer module design section.
The catalogue threshold reporting handles the reception
of catalogue thresholds reports from the on-line storage
subpackage. This report causes a catalogue threshold
report to be sent to supervisor's report printer.
4.2.5.4 M̲o̲d̲u̲l̲e̲ ̲S̲p̲e̲c̲i̲f̲i̲c̲a̲t̲i̲o̲n̲
This section contains the module specification for
the module contained in the supervisor command sub-package.

4.2.5.4.1.1 F̲u̲n̲c̲t̲i̲o̲n̲a̲l̲ ̲S̲p̲e̲c̲i̲f̲i̲c̲a̲t̲i̲o̲n̲
This module receives external supervisor commands,
MMS threshold warnings, dump response from dump coroutine,
off-line reports from the off-line retrieval coroutine,
and catalogue threshold reports from the online storage
coroutine. After reception the proper action is performed
by calling a certain module.
