in reply to Text file updation

Try using CODE tags around your code samples it does help to make the post a lot more readable.
Also use the -w flag on the shebang line and ALWAYS use strict;
Have a look at the CGI.pm module it will be your friend

Hi all experts, I had written a code as follows. 
#!/usr/bin/perl 
print "Content-type: text/html\n\n";
open (HANDLE,"/usr/fweb/catch/yy.txt");
@datasinfile = <HANDLE>;
close(HANDLE);
foreach $say (@datasinfile)
{
    @sur = split(/\n/,$say);
    push(@sur1,@sur);
}
foreach(@sur1)
{
    my($val1,$val2)= split(/:/,$_);
    push(@val,$val1);
}
print <<ht;
<html><head></head><body><form name="del" method="POST" action="/cg-bi
+n/test3.pl">
ht
;
$i=0;
foreach $v(@val)
{
    $var="<input type=\"checkbox\" name=\"chk$i\" value=\"$v\"$v";
    $i++;
    print $var;
}
print <<ht1;
<input type="Submit" name="delete" value="delete">
</form></ body><html>
ht1
;

 
yy.txt file format ---------------------
one:pass
two:fail
