By separating the application into smaller parts, you can easily identify the tools needed to complete the application. Part of this process consists of identifying the Callable Library routines that will be called.

In some applications, the Callable Library is a small part of a larger program. In that case, the only ILOG CPLEX routines needed may be for:

In other cases the Callable Library is used extensively in the application. If so, Callable Library routines may also be needed to:
