Hi Gerry,

The YYMMDDHH syntax is a GEMPAK construct, not an LDM one.

The LDM supports the 'strftime' syntax for assigning years, hours,
minutes based on the product creation time and another syntax based on
the real time clock.  The LDM reference for the various time-based
syntaxes is:

http://my.unidata.ucar.edu/content/software/ldm/ldm-6.3.0/basics/pqact.conf.html

Here is one example of how we use this to file NGRID (NOAAPORT higer
resolution model output in GRIB2 format):

#
# catchall
NGRID   ^_ELSE_$        FILE    data/ngrid/%y%m%d%H_else.ngrid

The directory listing in this case looks like:

cd ~ldm
ls data/ngrid/
200507111200.ngrid              200507121200.ngrid_eta
200507111200.ngrid_dgex-ak      200507121200.ngrid_eta-ak
200507111200.ngrid_eta          200507121200.ngrid_gfs
200507111200.ngrid_eta-ak       200507121200.ngrid_ndfd
 ...

>Where'd I go stupid?

The same place the rest of us went... old age ;-)

>Thanks, gerry

No worries.

Cheers,

Tom
