I do not know enough about your application to be sure this will work 
for you but have you considered reversing the index and content? 
Provided the names were unique, you could enter
set the cname["Peter"] of <object> to "student"
That is, you address by name rather than by Prof/student with the 
content being their title.

This way you do not need to know which is the next index for an entry 
but you are still able to recover the title for any student or in a loop 
the list or count of Professors or students.

I thought this was one of the features of content-addressable arrays.
