Description:

This script is used to compute a checksum for a given SSCC number. You can also produce a nice text representation using this calc. Works great with Brian Dunning's Code128 solution.

"(" &
Left ( $$sscc ; 2 ) &
") " &
Middle ( $$sscc ; 3; 1 ) &
" " &
Middle ( $$sscc ; 4 ; 7 ) &
" " &
Middle ( $$sscc ; 11 ; 9 ) &
" " &
Right ( $$sscc ; 1 )

Hey Andy!

Thanks for a this useful function. I made a little correction, because when the value of checksum gets 10, it should be 0. not 10. Right?

Case ( xDigit = 10 ; xPool & "0" ; xPool & xDigit )
