note naturalsciences <p>Hmm looked through my test script and yes it seems that the while(<>){$nextline=<>;$thirdline=<>} can actually be extended indefinetly. It is ugly but gets the job done.</p> <p>Why my scripts crashed seems to be of the undefined variables you get when your text files line number is not divisible by the number of your $nextlines. Then in the end you will get undefined variables for your $nextlines</p> <p> I need to get some control element that would terminate the script (or loop if I want to continiue with script) nicely. I think akin to - if any variables undefined exit loop, in the beginning of the loop. Should stop it from panicking with unfavorable Eof situation.</p> 1007560 1007562
