mmmh... why not simply something like this?: s/*/* /g

    Because: Quantifier follows nothing in regex; marked by <-- HERE in m/* <-- HERE / at ...

    With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    "Science is about questioning the status quo. Questioning authority".
    In the absence of evidence, opinion is indistinguishable from prejudice.

      okey, okey, it was about the idea not about the execution. The idea is that you could wish (or not) to make the replacement before populating your array. It depends on your specific case or goals

      Replacing a special character by something, full version

      while (<DATA>){ s/\*/* /g; print }; __DATA__ ******************* ********************

      Returning to the question

      I have an array with some special character like '*' and i want to print " " (space ) every where I find this '*'
      if($dlog2[$co] eq '*') { print $fh " ,"; }

      By "print everywhere" I'm understanding (maybe incorrectly) "everywhere in my array". You are not printing to your array. You are printing to a filehandle that contains and points to... well... who knows. Scalar. Not an array.

      If you want to modify your array, the idea could be: if some element of my array eq to '*' reasign again this element to ' '

      if($dlog2[$co] eq '*'){ $dlog2[$co] = ' '}

      Or maybe, to clean your problematic characters before, with a global replacement, and forget about the '*' in your file.
