The program returns six error codes

two
digits each. The
first

codes) codes are expected
to
be 00.
If
they
are not 00, they are the system error
codes,

The first error code is
from
a search
to
file 30.
The second error code is
from
a mark

to
mark

two
records each.

The third error code is
from
another
search
to
file 30 and a
write
header
command
to
this file.
The fourth error code is from a write
and read
of
data
to
file 30.
The fifth error code is
from
a read
of
the data on file
30
after
it
was erased
during the read operation. This error
code should be 09. This is the first
error code expected
to
be other than

The sixth error code
is
from a search
for
file
30
after the

track is
erased. This error code should be 04.
