Material Format

Hi all,

I ahve a small question, I am getting an input file which has materials in it but the format of the material is not fine, so can you please tell me a function module which will change the input materials in the desired manner, for example if the material coming is in the lower case should convert it in the upper and if matrial no. is not of length 18 then it shld also do this.

Thanks
