Padded zeros which is removed need to be replaced by spaces

Hi Friends,

My requirement in XI is : Padded zeros which is removed need to be replaced by spaces.

for removing padded zeros I used the UDF:

int i = Integer.parseInt(a);

return (Integer.toString(i));

It is working fine.

Please help as how to go abt in coding : whatever zeros get taken off , need to be replaced with spaces.

Thanks in Advance,

Meghna.
