@RudiC:
I don't really get the END section of your code. Specially the "tmp[2]" !??? And what is the separator in "split(line[i],temp)" ? Is it "\n" by default ?
I tried to modify your code in the case I have a third field specifying subgroup in the input file:
Code:
1%2%3%4%;AA;1
5%6%7%8%9;AA;1
1%2%3%4%5%6;BB;2
7%8%9%10%11%12;BB;2
13%14%15%16%17%18;BB;3      # note te third field is different then the previous "BB" groups

and obtain that at the end:
Code:
1%2%3%4%;AA;1;1-5%2-6%3-7%4-8%0-9%     # unchanged
5%6%7%8%9;AA;1;1-5%2-6%3-7%4-8%0-9%     # unchanged
1%2%3%4%5%6;BB;2;1-7%2-8%3-9%4-10%5-11%6-12%     #unchanged
7%8%9%10%11%12;BB;2;1-7%2-8%3-9%4-10%5-11%6-12%     # unchanged
13%14%15%16%17%18;BB;3;13%14%15%16%17%18  # $4 is same as $1 as this record is the only one in "BB;3" group

I changed your previous code as follow:
Code:
BEGIN{FS=OFS=";"}
         {line[NR] = $0
          a = split ($1, b, "%")
          for (i=1; i<=a; i++)
                {b[i]=b[i]?b[i]:"0";
                 if ((!MIN [$2$3,i]) || (MIN [$2$3,i] > b[i])) MIN [$2$3,i] = b[i]
                 if ((!MAX [$2$3,i]) || (MAX [$2$3,i] < b[i])) MAX [$2$3,i] = b[i]
                }
          if (a > maxfld[$2$3]) maxfld[$2$3] = a
         }
         END    {for (i=1; i<=NR; i++)
                  {printf "%s;", line[i]
                   split (line[i], tmp)
                   for (j=1; j<=maxfld[tmp[3]]; j++)
                      printf ("%s-%s%%", MIN[tmp[3],j], MAX[tmp[3],j])
                   printf "\n"
                  }
                }
