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<br>";
$i++;
print $var;
}

print <<ht1;
<input type="Submit" name="delete" value="delete">

</form></body><html>
ht1
;

yy.txt file format
---------------------
one:pass
two:fail
three:success
four:average
