Hi, I was trying some perl regex and got a bit stuck while trying to print index values in ranges. Have a look at my code. 


#!/iusr/bin/perl

open(FH, $ARGV[0]) || die("Cannot Open:$!");

while(<FH>){

   $char = '-';
   $offset = 0;

   $result = index($_, $char, $offset);

   while ($result != -1) {

         print "Found $char at $result\n";

         $offset = $result + 1;
         $result = index($string, $char, $offset);

  }
                  
}

This code prints the location of "-" wherever it finds... e,g

A-----B

if it finds this character it will print the location 5 times.

found at 2

found at 3

found at 4

found at 5

found at 6

I wanted to print the range when it finds this type of case.

Means

found at 2 to 6

Any suggestion ?

Thanks in advance
