Robert,

At one point I thought that the number of AREA files had been increased
from 9999 to 999999.  This would mean that the AREA file naming would
be:

AREAnnnn
AREnnnnn
ARnnnnnn

I don't know if this really happened or not, but you might want to play
with it.

If it still exists, yes.

I agree Aargh!

Let me know what you find out about the ARnnnnnn possibility.  The way
I would do this is by upping the range of AREA file numbers in the
beg end portion of a DSSERVE:

DSSERVE ADD TEST/IMAGES AREA 1 999999 ...

Robert,

OK.  The "funny" thing is that when you do a DSSERVE command
and use DIRFILE for an image dataset that does not use AREAs (name or
format), then the R1 and R2 entries in RESOLV.SRV get set to 1 and
999999 respectively.  Looks like that is some thinking towards
expanding the AREA file naming in the future.

OK.
