Antonio, the underlying problem in [MOUNT96]MOUDK2 has been fixed on 18-OCT-2000 by making sure, that VCB$B_BLOCKFACT is at least 1 to prevent the UNXSIGNAL INTDIV error in F11BXQP. This solution is present in OpenVMS VAX V7.3 or any patch with a VMOUNT.EXE linked later than 18-OCT-2000 (e.g. VMOUN01_072). Volker.
