l/km is litres per kilometer, not the other way around. The smaller the
number the better the petrol consumption.

And FWIW, the UK still uses mpg, albeit we are in Europe. [...]64_6Sep200511:27:[log in to unmask]

$big_wa1 (AFAIK, millicode included by the compiler) traps when
trying to access virtual address $a18.128 .

Unable to debug BATCHMAN life and with source code it is hard to
tell, but I will guess that $a18.xxx  stands for a file opened by
BATCHMAN.

It could be a user mapped file, in which case I remember there was
an issue accessing these, if they were attached to an online backup.

Maybe when you retry successfully, the CCC account has already been
stored and the files are no longer shadow attached ?

If your system is on 7.0 or 7.5 than it cannot be that problem,
on earlier releases you need MPELXA1 (see JAGad62640 ) or higher.
