Hi Kwan,

Sorry for the tardy reply...

Thanks for alerting me to this.  It looks like someone did some renaming
of directories along the way, and I never updated the dataset definitions
for the 1KN0R-NAT, 2KN1P-NAT, and 4KNTP-NAT datasets.  I have corrected
the problem and am testing as I write this.

I had never tried SFCLIST listings in this short time window before, so
your report is a new one for me.

Taking a quick look at the online help for SFCLIST, I am reminded of the
SPAN= keyword's effect on the listing.  The default is SPAN=DAY which
seems to have resulted in the expansive listing you got using SFCLIST
for the 23:50 - 23:59 interval.  I suggest changing the behavior of SFCLIST's
invocation of PTLIST by including the SPAN=TIME keyword sequence.

Also, to see what keywords are being set by SFCLIST for the PTLIST invocation,
include the DEV=CCC invocation on the command line.  This should shed some
light into what SFCLIST is doing "for you" as opposed to what you want.

Please let me know if the above is clear enough...

Cheers,

Tom
