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? eric@zen.maths.uts.edu.au -- eric@zen.maths.uts.edu.au Eric Lindsay, Sch of Maths, Uni of Tech Don't take life too seriously. It is only temporary.
