bash doable like this:

--- code ----
word="abc"
newword=""
lcase=( a b c d e f g h i j k l m n o p q r s t u v w x y z )
ucase=( A B C D E F G H I J K L M N O P Q R S T U V W X Y Z )

for (( i=0 ; i<${#word} ; ++i )) ; do
        letter=${word:$i:1}
        for j in ${!lcase[*]} ; do
                letter=${letter/${lcase[${j}]}/${ucase[${j}]}}
        done
        newword="${newword}${letter}"
done

echo "${newword} == ucase( ${word} )"
--- code ----

but why not 

`tr abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ`

^^^ this one is chosen from MySQL configure script so it should be 
portable (or as often I'm missing something ?)
