Correction 1. There seem to be a problem when you have a master database file. Here are the changes I made which fixed it: Change file fingerReviewer only! Appended are the uncorrected/corrected lines. 1. Quote the path to the master reviewer database 2. Comment out the echo command line 168 3. Add exclamation to the "cat" command line 171 4. add i=0; before RS line 173. 51c51 < set MRDatabase = /u/adam/I/DIRECTORY/ADDRESSES/database --- > set MRDatabase = "/u/adam/I/DIRECTORY/ADDRESSES/database" 168c168 < echo " ====> LLine = $LLine " --- > # echo " ====> LLine = $LLine " 171c171 < cat < $tmpf2 > $tmpf --- > cat < $tmpf2 >! $tmpf 173c173 < awk "BEGIN{ RS = $delimiter; ORS = $q$q } \ --- > awk "BEGIN{i=0; RS = $delimiter; ORS = $q$q } \ END correction 1.
