Can anyone confirm if this behaviour of LBYTES occurs on a standard QL
or only on QPC2 (I only have a QPC2 setup at the moment and too lazy 
to fetch the QL from the attic)

With SBYTES you can do something like SBYTES ram1_test,address,0 which
creates a not very useful zero length file. But if you try to LBYTES
it back with LBYTES ram1_test,address you get the error message 'end
of file'

I spent a while tracking down a bug reported in one of my programs
where I was told it gave the "end of file" message and it turns out it
only happens with 0 length files (quite why anyone would want to
LBYTES a zero length file I'm not sure, but there we are!)
