And when 5.10 arrives
#!/usr/local/bin/perl5.9.5 # use feature ":5.10"; use strict; use warnings; print "content-type: text/html\n\n"; my @userArray = qw(batman robin joker); my @userArray2; #this is a null array my @mainArray = (@userArray, @userArray2); my @set; # A loop, just for this example... for(@mainArray) { when ( ! defined $_ ) { next } when ( /^$/ ) { next } default { push @set, $_ } } say "@set";
I of course do not mean this as a serious (Use this in production) reply to the op.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
