For zero padding in ksh, use the typeset command:

Code:
$ typeset -RZ5 x
$ x=25
$ echo $x
00025

Mapping it to your case:
Code:
$ length=15
$ value="1234567890"
$ typeset -RZ${length} value
$ echo $value
000001234567890

Hi guru...

typeset worked when the "value" has some value in it...
if the value sometimes empty ... then it should create the passed length zero's...
But typeset is giving spaces ...Help me on this

In case this works:
Code:
$ cat temp.sh
length=15
value="1234567890"
printf "%0*d\n" $length "$value"

value=""
printf "%0*d\n" $length "$value"

$ ./temp.sh
000001234567890
000000000000000

Sorry about that. Smilie

If typeset does not work, one thing you could try (adjusting syntax if needed for ksh) is:
Code:
if [ -z "var" ]; then
  echo 00000000000
else
  typeset -RZ${length} value
  echo $value
fi
