I did test this with the original SCCS and it failed.
I did not test it with CSSC.

SCCS correctly detects the null byte that the test file from test fa11 inserts.

The test is then considered as failed by your script and this is why I am 
asking.


BTW: I verified that SunOS-3.5 does not support encoded files, so this seems to 
be a feature from SunOS-4 (most likely as a result of the efforts for NSE that 
contained the first project oriented SCM [based on SCCS] and that came up to 
the end of the SunOS-3.5 period shortly before SunOS-4.0 came out).

So the question is:

fa11 fails with the original SCCS, does it fail with CSSC too?

It is intended that this test should fail?

BTW: When I should discuss the behavior of SCCS, I would like to be able to 
tell SCCS not to automatically switch to binary mode (e.g. via an environment 
varibale to catch the case where the only reason for bein "binary" is a missing
new-line character at the end of the file.
