문제

Following is a portion of the script I am using to send HTML page as chunked response. However upon running the script throws compilation errors like :

Number found where operator expected at nph-99_1_1_18.pl line 19, near "print "233" (Might be a runaway multi-line "" string starting on line 18)

#! /usr/bin/perl

print "HTTP/1.1 200 OK\n";
print "Connection: Close\n";
print "Content-type:text/html\n" ;
print "Transfer-Encoding:chunked\n\n" ;
print "96\r\n";
print <<EndText;
<html>
  <!-- this chunk is 150 bytes in length-->
  <head>
         <title>Document Title</title>
  <link REL="StyleSheet" TYPE="text/css" HREF="example.css">
  </head>

<body>
EndText
print "\r\n\";
print "233\r\n";
print <<EndText;
<!-- this chunk is 563 bytes in length-->

해결책

There's an overhead backlash \ in one of your print statements. There's another one where you copied that line further down, too. It escapes the closing ", so everything after it is interpreted as a string.

<body>
EndText
print "\r\n\"; # <--- HERE (and also further down)
print "233\r\n";

Do you write your code with an editor/IDE that has syntax highlighting? Turn it on and make strings stick out. That way it will highlight you everything after the escaped " as a string and you'll not overlook this again.

Also, you should use strict and use warnings.
