# May 20, 1999.  Check for tow number with the word Tow in it and try
#	to isolate the real tow number, e.g. cruise EN263.  rcg
# May 29, 1999.  Need to work on tow vs cast/comment test.  There
#	are problems with non-numeric values.  Not repaired yet.  
#	Need to repair comparison in numalpha to test correctly for
#	non-numeric characters.  rcg
# June 4, 1999.  Use list rather than listgb program.  rcg
# June 8, 1999.  Add additional code to handle tow & cast numbers with
#	non-numeric characters. rcg
# October 3, 2001.  V2.12so - Set up for Southern Ocean.  Based on GB version
#	Naming convention for tow and 
# December 24, 2001.  V2.13ZG. Modified for ZooGene data.  rcg
# July 10, 2006.  V2.15CM  Modify for CMarZ data
#
# Jan. 30, 2012. V3.0BC Modified for BCO-DMO data. Scripts

# February 13, 2012. V3.01BC Divide comment so it fits on two lines. rcg

# November 7, 2012. V3.1  Modified to account for those instances when.  
# 	cruiseid column is missing from eventlog.  mda + rcg 
# February 21, 2014.  V3.1DM3  Copied over to dmoserv3 to serve ctd_mocness data
#       that lives there.  mda
# Apirl 11, 2014. V3.2. Change where the script finds the make_log_entry routine
#	so it finds it from the "library" area. rcg
# Apirl 11, 2014. V3.21. Add code to handle no event log url's being used
#	since there is no station information. Improve subroutine looking at
#	the eventlogs to declair all variable names. Check that there are data
#	for all the field names specified for this level, level 2. rcg
