My second edition camel book shows how to do it. The critical points are: 1) put the output of the format statement into a variable, 2) eval that variable. Here is a piece of demonstration code. I have tried to make it readable, it is surely not the most compact version possible.
$data = qw( aaa bbb ccc );
$fields = scalar @data;
$data_fields = "";
map $data_fields .= '"' . $_ . '"', @data;
$format = "format STDOUT = \n"
. "@<<< " x $fields . "\n"
. $data_fields . "\n";
. ".\n";
eval $format;
write;
HTH, --traveler

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).
