      problem with chomp

      I'm having this weird problem with chomp
      I want to get all the numbers out of a file that looks like this
      1,2
      4,3,2
      and have the first number point to an array of the others in a hash
      I'm almost able to do this except for the fact that a '\n'
      get ad to the last number,
      I'm trying to get rid of it but somehow chomp just won't work
      code :
      Code:
      open (DataBase,"voorwaardelijk.txt");
      ...

        a hash of arrays

        Hi all,
        I'm having a problem getting the length of an array that I've put in a
        hash here's my code

        Code:
        $voorwaardehash{$key} = [@getallen];
		
		@lengte = $voorwaardehash{$key};
		
		print "--".$#lengte ."\n";
        now this looks fine to me except that ik keeps returning 0 instead of the true length of the array thats at the key

          replied to help with regular expressions
          in Perl
          I have to chop because when perl somehow adds a character after the concatenation and that screws up my searching expression when I'm trying to find what i found here in text file...

            help with regular expressions

            for a program i'm makin I need to be able to analyze lines like the following one

            1 waarschijnlijk neiging tot suikerziekte ccaggcccac ctggagactc

            and split it up in a part that containes the number
            a part that containes the text
            and as a last part the dna sequence ccaggcccac ctggagactc

            now i can do that with the following code

            Code:
            # haal de ziekte codes er uit
		if($line
            ...

              thanks for the reply
              youre link to
              http://serach.cpan.org/
              doesn't seem to work so I don't know what you mean with the module thing.
              It's not really homework, it's more of an exercise I was advised to try out
              on.
              this the code i've written to get the evil sequences out of the database,
              I don't really have any usefull code yet on the analyzing section as Im still trying to figure out how to do it...
