interesting question about variables

[Martin A. Hansen]

hi

i have a loop containing the following block of code. however, first time the loop is 
run, $text_link is empty, which it shouldn't be. i cant move the declaration of 
$text_link above the if statment, because then the $figure_name would be empty.

now i guess im really missing out on something fundamental here, since i cant figure 
out how this issue is solved!

any suggestions will be appreciated

:o)

if ( ( $hash -> { $paragraph } ) =~ s/###(\w+.*\.jpg)###/($text_link)/ ) {
  $figure_name = $1;

  $text_link = $cgi -> a({-href => "javascript: window.open('$pix_dir/$figure_name'," 
                                 . " '', "
                                 . " 'status=yes, "
                                 . "  resizable=yes, "
                                 . "  scrollbars=no, "
                                 . "  width=530,"
                                 . "  height=380'"
                                 . ");
                                   void('');"
                           }, "Fig $figure_number" );
                          
  $figure_number++;
}
