Hmm. Are you sure you did a cut & paste instead of re-typing the code. It works fine for me, I just removed the CGI components: 
print <<ENDHTML;
<HTML>
<HEAD>
<TITLE>CGI Test</TITLE>
</HEAD>
<BODY>

<H2>Congratulations!</H2>

<P>We're glad to see you $firtName, members of the $lastName family ar
+e always welcome here. It's hard to believe that you're already $Age 
+years old. My how time flies.</P>

</BODY></HTML>

ENDHTML

And it runs fine : 
$perl -c foo.pl
foo.pl syntax ok
$foo.pl
<HTML>
<HEAD>
<TITLE>CGI Test</TITLE>
</HEAD>
<BODY>

<H2>Congratulations!</H2>

<P>We're glad to see you , members of the family are always welcome he
+re. It's hard to believe that you're already years old. My how time f
+lies.</P>

</BODY></HTML>

ENDHTML
