I have translation rule like this below, i understand the rule that replaces the first digit 9 with 4 what is the significance of \1 at the end , I see in some rules it is \3 , \2 etc i am not able to corelate that to anything. May be a silly one but can anyone answer soon as we have a number change in Qatar.
rule 1 /^9\(.*)/ /4\1/
