We have had many instances of damaged directory and fat tables on 
floppy disks used by our students running JPI Modula2 v1.14 and v1.16.  
The students are on a Novell 2.15 network, and normally don't have access 
to a hard disk, so all their work files are on floppy.  I originally 
assumed that JPI were checking for a (hardware provided) disk change 
signal, which of course does not exist on older style XT disk controllers, 
and we reduced the incidence of problems by telling students never to remove  
their diskettes until after they had exited from Modula 2.

Now I seem to have evidence of the same problem on an AT (which does have 
disk change signals).  Has anyone else seen this?  Is there anyone else 
actually running this software under similar conditions?  Does anyone know 
if the same thing happens in Version 2?

Don't take life too seriously.
It is only temporary.
