But a redo (just like next and last is just
a glorified goto.
I consider this statement blatently false and missleading.
- goto FOO
causes is designed to cause
execution to jump to the
lable FOO anywhere in your script (provided no
initialization would be neccessary to get there)
- redo FOO
will only work
if the is designed to cause execution
to jump to label FOO if it exists
at some surrounding loop block. (allthough it
will work w/warning if the label applies to some
dynamicly surrounding loop)
This typo generates an error...
perl -le 'BAR: print 1; BAZ: for (2..3) {print; redo BAR; }'
This typo causes an infinite loop...
perl -le 'BAR: print 1; BAZ: for (2..3) {print; goto BAR; }'
(Updated to be less pedantic... the point is, goto
is for arbitrary jumping, redo is for controlled jumping to
the begining of a loop. Could you live w/o redo if you had
goto? yes. Does that mean you should just use goto and
not bother with redo? no.)

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).
