You have some basic misunderstandings. A String is just an array, so to 
assign anything to Word, it must be exactly 31 Characters long. Why 31, 
when you're only reading 30 Characters? Word (31) is undefined.

Presumably you're doing this to learn Ada. You should work through a 
text or tutorial so you understand the basics of the language before 
working on anything like this. Then when you have problems they'll be at 
a suitable level for asking here. You can find both texts and tutorials 
on line at adapower.com and adaworld.com.

When you do get to that level, you'll find that reading words is already 
done for you. See PragmARC.Word_Input and the various sorting packages 
that are part of the PragmAda Reusable Components. The PragmARCs are 
available from
