a) Fundamental properties of the Standard Software
which shall be considered in depth during the design,
development and production are its quality integrity
and flexibility.
b) The Software shall be structured in a clearly identifiable
hierarchical way. The design shall maintain maximum
isolation and independence between units of all
types during program design and implementation
and durin on-line operation of the system.
c) The Software shall be carefully documented in parallel
to the design during the production phase. The
documentation shall form part of each deliverable
software package and conform to the documentation
standar specified elsewhere in this document.
d) In the construction of program code, clarity of
meaning shall be a major consideration. When writing
the program code comments shall be inserted to
aid comprehension and improve the readability.
e) It i mandatory that instructions and constants
of the system standard software shall not be modified
during runtime. Within each software module/program
the program code and constants shall be segregated
from the modifiable data. The data areas of a moule
shall be contigous and all exchange of data between
different modules shall take place either through
well-defined shared data areas or by value passing.
f) The System Standard Software shall be implemented
as a well structured suite of code nd data modules
incorporating sufficient hardware protection and
software checking to ensure that the System Software
itself can achieve and maintain the status of high
integrity, trusted code with respect to the Applications
Software. Preferably te System Software shall reside
in read-only memory.
g) Sufficient validity checks must be applied at appropriate
points in the System Software/Applications Software
at Compile time and/or run time to ensure that
the integrity requiements (refer section 8) will
be met, attention however, being paid to maintaining
efficiency.
h) Recovery procedures after system failure shall
include the validation of the integrity, i.e checksumming
of software, of the operating system softw
