( #3333=superdoc: print w/replies, xml ) Need Help??

You really need to get a good book on perl. Start on page one and work your way though.
Posting bad code over and over again is not going to get you anywhere!
There are numerous problems with this code. No strict, no Warnings.

It all boils down to:
$dat0 = 'a.txt'; open( DAT, "$dat0" ) || die ("Could not open file!"); @all = <DAT>; # I'm not enven sure what perl will do when you open the same file han +dle # twice without closing, I would assume it would close the first for y +ou, # but it's just bad. open( DAT, ">$dat0" ) || die; # You never write back to @all so you are doing nothing. print DAT @all; close(DAT);
If you want to learn, we can help you, but you have to learn to walk before you run.

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.
