virtualweb has asked for the wisdom of the Perl Monks concerning the following question:

Hi: I splitted an array containig a word because I needed to change some of the elements, (some letters): $Tne_Word = 'antidisestablishmentarianism'; @splitted_word = split(//, $Tne_Word); when I print to the browser @splitted_word it reads: a n t i d i s e s t a b l i s h m e n t a r i a n i s m How do I make it look whole again, (without the spaces) Thanx VirtualWeb

    Set the list seperator to the empty string
    use strict; use warnings; my $Tne_Word = 'antidisestablishmentarianism'; my @splitted_word = split(//, $Tne_Word); { local $"=''; print @splitted_word, "\n"; }
    Update (thanks to jwkrahn and ikegami)
    use strict; use warnings; my $Tne_Word = 'antidisestablishmentarianism'; my @splitted_word = split(//, $Tne_Word); { local $"=''; print "@splitted_word\n"; }

      You changed the value of the $" variable but  print @splitted_word, "\n"; doesn't use the $" variable.   It does however use the $, and $\ variables.

      Not quite. That should be

      { local $,=''; local $\="\n"; print( @splitted_word ); }

      or

      { local $"=''; print( "@splitted_word\n" ); }

      See $,, $\ and $".

      However, using join is less error-prone, more natural, shorter and more versatile (you can use it when you don't want to print).

      print( join( '', @splitted_word ), "\n" );
        Ikegami: Thanx for your input a variation ofyourline of code did the trick @Make_Whole = join( '', @splitted_word ); I had tried the following prior to posting for help and hadnt work: @Make_Whole = join( //, @splitted_word ); It did work with commas however thanx again VirtualWeb
      Thanks for the correction jwkrahn and ikegami. The above response was obviously a bit too hasty. I intended ikegami's second variant. But it is probably better to use join, since the behavior does not rely on interpolation.
      I updated the code to correct the error.

    You actually split a scalar containing a word into an array.

    Have you tried using the substitution or transliteration operators?
