Re: String sequence characters and appending clarity

Because append and concatenate are not the same thing.

concatenate

Join together two objects. The resulting length is the sum of the objects' lengths.

append

Add the entire second object as one element to the first object. The resulting length is the length of the first object plus 1.

sequence A = {'a', 'b', 'c'} 
sequence B = {'d', 'e', 'f'} 
sequence C 
 
C = A & B --> {'a', 'b', 'c', 'd', 'e', 'f'}, length is now 6. 
-- You can see that each element of B has been 'added' to A  
 
C = append(A, B) --> {'a', 'b', 'c', {'d', 'e', 'f'}}, length is now 4. 
-- You can see that B has been added as a single element to A.
