Art,
Peter Neilley had an exchange with Chris Vandersip a few weeks back
dealing with duplication in the "weather" program. The suggestion was to
use the DBFILEing with the program instead of storing the obs in a text file.
Chris's message is in the ldm-users support archive:
http://www.unidata.ucar.edu/glimpse/ldm-users-list/4123 and others

GEMPAK and MCIDAS generally use the duplicate report to check for missing or
corrected data without overwriting the complete observation with an
abbreviated report.
