monks
I have to use this in file manipulation like,

              open(FILE,"....") or die $!;
              while(<FILE>)
              {
                //Here Change part has to come

               }
              close FILE

2)how to modify with in this file in while loop

1)how to open a file like >+ or +<?. From perldoc -f open: `You can put a '+' in front of the '>' or '<' to indicate that you want both read and write access to the file; thus '+<' is almost always preferred for read/write updates--the '+>' mode would clobber the file first. You can't usually use either` [download] Curiously enough I wrote an explicit example yesterday in a thread with almost exactly the same subject as this one...	[reply] [d/l]
