When j is equal to length(Tr), Tr(j+1) is one past the end of the array. How
to fix this depends on what exactly you're trying to do. There are likely
ways to do what you described without a loop, depending on the specific
details behind your individual numbers. Are they integer values? Are they
unique? What criteria are you using to generate the number -> letter
mapping? If you post more information to the newsgroup, people may be able
to offer more specific suggestions.
