Calculate Checksum

Hi,

I want to Convert my data into BARCODE FONT 128 B type..the data is like
example RBOR00332233, that requires a definite checksum character for each
unique data. Is there any function (inbuild or user-defined) pleaze forward..

I want to calculate "CHECKSUM" of MOD 104 which is compulsory to convert a
normal data into code 128..

Regards,

Safi.
