Diagnostics
Upon termination, each command returns two bytes of status,
one supplied by the system giving the cause for termination,
and (in the case of normal termination) one supplied by the
program. The former byte is 0 for normal termination; the
latter is customarily 0 for successful execution, nonzero to
indicate troubles such as erroneous parameters, bad or
inaccessible data, or other inability to cope with the task
at hand. The second byte is called ``exit code,'' ``exit
status'' or ``return code,'' and is described only where
special conventions are involved.
