Ah, thank you fellow monks for the insight. (actually, I tried tye's way, but it did not work then) Thus:
BEGIN{
unless (defined $ENV{APPLEJACK}){
$ENV{APPLEJACK}= "TRUEBLUE";
exec( $^X, $0, @ARGV );
exit 0; # we actually never get here
}
}
print "STARTING " . $ENV{APPLEJACK} . "\n";
prints:
STARTING TRUEBLUE

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).

or How to display code and escape characters
are good places to start.
