( #3333=superdoc: print w/replies, xml ) Need Help??
Thanks, synapse0 (and others who replied also) for the suggestions.   8^)

I'm not familiar with the eq 'lc' ? lc() : uc(); syntax from print OUT $uclc eq 'lc' ? lc() : uc();.   Would you be so kind as to explain how that works?

Here's what I ended up using.   Thanks again, and ++ to all who offered suggestions in nodes and CB!

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).
