( #3333=superdoc: print w/replies, xml ) Need Help??
The test for empty line has nothing to do with removing comments, so there's no need to check for it in the sub. I'd reverse the test and do away with the next:
sub RemoveComments { my $line=$_[0]; $$line =~ s/#.*$//; # No need for a separate pattern match } .... while ($temp=<INPUT>){ RemoveComments(\$temp); if ($temp =~ /\S/){ ... some other code ... } }
but you could also do
while ($temp=<INPUT>){ RemoveComments(\$temp); next if ($temp !~ /\S/); ... some other code ... }

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.
