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

I don't know why, but on a hunch, I tried this change:

#! perl -slw use strict; sub recurse { print ">> '${ $_[ 0 ] }'"; if( length ${ $_[ 0 ] } ) { #recurse( \ substr( ${ $_[ 0 ] }, 1, -1 ) ); #old recurse( \( my $boo = substr( ${ $_[ 0 ] }, 1, -1 ) ) ); #new ${ $_[ 0 ] } = " ( ${ $_[ 0 ] } ) "; } print "<< '${ $_[ 0 ] }'"; return; } my $str = 'aaaaaaaaaa'; recurse \$str; print $str;

and it worked. I leave it up to you to explain it (cause I'm going home!)

I'm don't think this is the output you want, because it would be a very convoluted way of getting it. But you didn't specify what you wanted.

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.
