I am in the midst of building my own message board one piece at a time. in this problem there is a message board with one link to a subject. The script opens the text file to be searched, stores it in an array, and searches the array for the section to be displayed on the new page. At the momment this code is not finding the search string, and thus displays nothing, except when you put an identical print statement between the if and while statements. Here we go: 
#!/usr/bin/perl
print "Content-type:text/html\n\n";

#http://xxrainxx.tripod.com/cgi-bin/mboard.html test page
#http://xxrainxx.tripod.com/cgi-bin/postall.txt text file


open (INF,"postall.txt")  or dienice("Couldn't open postall.txt for re
+ading: $!");

$subject = $ENV{'QUERY_STRING'};
$subject =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C",hex($1))/eg;
$subject =~ tr/_/ /;

@b = <INF>;

close (INF);

print <<"EndHTML";
<html><head><title>$subject</title></head>
<body bgcolor="#000000" text="#DDFFDD" face="Verdana,Helvetica,Arial">
+\n
$ENV{'QUERY_STRING'}\n<br>
$subject\n<br>
<br>
<blockquote>
Here's the message:\n<br>\n<br>\n
EndHTML

print "$subject this is what I'm looking for<br>\n";

for ($x=1;$x < scalar @b;$x++) {
    
    if($b[$x]=="***Begin $subject"){
        
        while ($b[$x]!="***Begin Here***\n"){
            print "$b[$x]<br>\n";
            $x = $x + 1;
        }
    }
}
#foreach $line (@b){
#    chomp($line);
#    print "$line<br>\n";
#}

# I removed a section of html when posting because last time closing t
+he textarea broke the preview text field.

sub dienice {
   my($msg) = @_;
    print "<h2>Error</h2>\n";
    print "$msg;\n";

}
