G'day rocketperl,

No. You're almost there, though: try $i += 3

All of those types of operators are described in perlop - Assignment Operators. Actually, you'd do well to, at least, scan through all of perlop to learn what operators Perl provides.

    Thank you so much. Can i store the position value in another variable like this? my $index1=($index+=1); my $index2=($index+=2);
      "Thank you so much."

      You're welcome.

      "Can i store the position value in another variable like this? my $index1=($index+=1); my $index2=($index+=2);"

      You need to try this yourself! If you make mistakes, that's great: you'll learn something and, hopefully, won't make those mistakes again. I've provided you with specific documentation for those operators as well as more general documentation for all operators: please read it. hdb (in Re: is $i=+3 valid?) has recommended you experiment and has even provided sample code: heed his advice.

      If, after trying this for yourself, you get stuck or don't understand some aspect of what's going on, then come back and ask. However, before asking, ensure you have read "How do I post a question effectively?" and that your post follows its guidelines.

      Furthermore, I recommend you go over your previous posts (that's seven threads) and read the advice given. There's a distinct trend of: help being asked for; help being given; help being ignored; same help being asked for again; frustrated monks pointing you back to help that was given only a day or two before.

      We're happy to help if you show some effort yourself.
