I have no idea what you like to test here, this is why I asked you.....

I am not sure what you are replying to as you reply to a mail with the subject:
"Test binary/auto.sh fa11" but this is a thread with a different subject. I 
thus reply to the _content_ which is related to "Test binary/auto.sh fa11" but 
not to the subject from this mail.

I have not idea what you understand by "BOL" and a character with the value \001
does not appear in this test.

You write four characters into a file : 'x' a "\000' (nul) a 'y' and a new line 
('\n').

You then call:

        admin -iinfile s.infile

As the file contains a null character, SCCS-5.0 and above will automatically 
switch to binary mode. Your recent answers claim that CSSC should do the same.

Your next test calls:

        prt -f s.infile

and as this reports an encoded file, the test fails.

>From everything you wrote, this test is expected to fail with both SCCS and 
CSSC.

Question: why do you write a test that aborts the test suite because it 
would require SCCS to encode a _binary_ file as text file in order to pass?
