# modification history
#  5 Aug 1999 ?        - original script
#    MAR 2000 ?        - Modified for implementation of the IBM SP
# 20 Mar 2013 JWhiting - ported for use on WCOSS (linux) platforms:
#                         set to run under ksh
#                         no logic changes
#  9 Sep 2014 JWhiting - removed echo reference to 'IBM SP'
#                        trapped RUN=gdas to set correct file prefix
# 18 Apr 2017 DStokes  - Updated to handle gdas file with prefix gdas or gdas1
#                      - Added logic to have job fail if the dump_alert_flag
#                        file is not available or cannot be printed via cat.
#                      - Modified to check dump_alert_flags with $tmmark suffix.
