( #3333=superdoc: print w/replies, xml ) Need Help??
Sorry I forgot to mention this was only a snippet of the whole program, and it wasn't exactly accurate to what I had in actual program.
I just wanted to illustrate what the direction in which I was headed for solving this.
Sorry also that I couldn't just paste the whole code.
Anyway in my actual program it turned out that the issue was the scope of the $dir variable in my subroutine as far as I can tell.
The program works correctly now.
I guess it would be better (also faster?) if it is done in the main program and not in a subroutine, but it was easier for me to follow what I am doing by writing subroutines. I am also not sure how to do what you mention.

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 or How to display code and escape characters are good places to start.
