Bounded string is a generic type which must be instantiated to
a preset/compile-time maximum length, while there is no such 
upper limit for unbounded strings. They can be set to any length 
at run time, given enough RAM.

Another difference is that unbounded strings will allocate
space for itself on the heap, and will allocate more (or less)
storage as needed. This is automatic, and the language standard 
states that all memory used by unbounded strings should be automaticly
released on exit of scope and assignment. 

Bounded strings should not use pointers and dynamic allocation due to 
an implementation advice in The RM.
