10 Program Structure and Compilation Issues

  1. The overall structure of programs and the facilities for separate compilation are described in this section. A program is a set of partitions, each of which may execute in a separate address space, possibly on a separate computer.
  2. As explained below, a partition is constructed from library units. Syntactically, the declaration of a library unit is a library_item, as is the body of a library unit. An implementation may support a concept of a program library (or simply, a "library"), which contains library_items and their subunits. Library units may be organized into a hierarchy of children, grandchildren, and so on.
  3. This section has two clauses: See section 10.1 Separate Compilation, discusses compile-time issues related to separate compilation. See section 10.2 Program Execution, discusses issues related to what is traditionally known as "link time" and "run time" -- building and executing partitions.
