Hm, I suppose you meant something like this:

my @globalarray;
foreach my $filename (@ARGV) {
   open my $fh, '<', $filename or die "$filename: $!";
   my @temparray = <$fh>;
   push @globalarray, @temparray;
   close $fh;
}

Guess you could learn the use of "push", that's about the only thing. It's used to append a scalar or a whole list to the end of an array. "pop" does the opposite and takes one scalar off. shift and unshift work the same, just on the start of the array.

• 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).
