reuse
reusability

   Using code developed for one {application program} in another
   application.  Traditionally achieved using program libraries.
   {Object-oriented programming} offers reusability of code via
   its techniques of {inheritance} and {genericity}.  {Class}
   libraries with {intelligent browsers} and {application
   generators} are under development to help in this process.
   {Polymorphic} {functional languages} also support reusability
   while retaining the benefits of {strong typing}.
