    Do it in separate blocks, with the code in the middle.

    val=Mumbai
file=pkll1.htm

cat <<EOF1 > $file
<html> 
<head>
<title>HTML</title>
</head>
<body>
<h1>$val</h1>
EOF1

while read line; do
  val1=`echo $line`
  echo "<p>$val1</p>" >> $file
done < myfile.dat

cat <<EOF2 >> $file
</body>
</html>
EOF2
