Hi,

Being a beginning "Perl-learner", I want to do things the (most?) right/best way immediately.

I have a question about the right/best way to append items to an already existing array. This is my initial array: 
    $inputPathPrefix = "C:/Temp/xml";
    @inputfiles = (
        $inputPathPrefix . "/test1.xml",
        $inputPathPrefix . "/test2.xml",
        $inputPathPrefix . "/test3.xml"
    );

I would like to extend the array. Therefor, there are 2 ways of doing this AFAIK:

First method: 
        @inputfiles = (
            @inputfiles,
            $inputPathPrefix . "/test4.xml",
            $inputPathPrefix . "/test5.xml",
            $inputPathPrefix . "/test6.xml",
            $inputPathPrefix . "/test7.xml"
        )

Second method: 
        push(@inputfiles, $inputPathPrefix . "/test4.xml");
        push(@inputfiles, $inputPathPrefix . "/test5.xml");
        push(@inputfiles, $inputPathPrefix . "/test6.xml");
        push(@inputfiles, $inputPathPrefix . "/test7.xml");

Three questions:

1. What's the best/preferred/Perl-ish method?
2. Has the first method advantages over the second method or vice versa? What are the advantages, if any?
3. What's the habbit in case of initial array declaration and first method: put the comma's at the back or at the front?

Best,
