GOTO's and LABELS?!?!
Yeah, what about them? People easily balk at seeing a goto,
but not all goto's are evil. There are two famous papers on the
subject, Go To considered harmful, by E. Dijkstra (although
it was C. Hoare that give the paper a title), but that paper doesn't
say one should never use a goto - it warns for improper
use. And then there's of course Structured Programming with Goto.
By D. E. Knuth - perhaps the best Computer Scientist that ever lived.
Besides, aren't we all fond of next, last
and redo? They are nothing but gloried gotos.

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).

are good places to start.
