Apparently I left out the stripped down script:

find $4 -type f -name '[0-9]*'|xargs  awk '{ # set values from the command line
 
     RE1_p = '"\"$1\""' 
     RE2_p = '"\"$2\""' 
     RE3_p = '"\"$3\""' 
   }

   {
      if (FNR == 1) {
          in_header  = 1
          in_matched = 0
          RE1_l  = ""
          RE2_l  = ""
          RE3_l  = ""
      } else if (in_header && /^$/) {
          in_header  = 0
          if (RE1_l && RE2_l) {
              in_matched = 1
          }
      }
      if (in_header) {  # in header section
          if ($0 ~ RE1_p) {
              RE1_l = $0
          } else if ($0 ~ RE2_p) {
              RE2_l = $0
          }
      } else if (in_matched) {  # in body of matched message
          if ($0 ~ RE3_p) {
              if (! RE3_l) {
                        filename2=FILENAME      
                                sub(/^.*\//,"",filename2)
                                    print "-- \n" FILENAME
                  print filename2"|" RE1_l
                  print filename2"|" RE2_l
                        }
              RE3_l = $0
              print filename2"|"FNR"|" RE3_l
          }
      } else {  # in body of unmatched message
            nextfile  # GNU awk extension to skip to next file
      }
  }'
#    END {
#    print "RE1="RE1_p "\nRE2="RE2_p"\nRE3="RE3_p
#}'
echo "RE1=$1"
echo "RE2=$2"
echo "RE3=$3"
