Here's another way, based on your code:
#!/usr/bin/perl
use strict;
use warnings;
###
sub datestamp(){
use POSIX;
return strftime("%D %r",localtime);
}
my $var_day = datestamp();
###
print <<HERE, datestamp(), <<SECOND;
Variable interpolation works - Instead of the literal
text seen here, this variable's value is printed.
>>$var_day<<
But how do you do "function" interpolation?
The next line prints itself literally, instead of
being substituted with the function's return value.
Is there some other way of writing this that does what I want?

here's some more text...

SECOND
print "done!";

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).
