Chapter 3 Intrinsic Tasks

This chapter is a quick reference for locating intrinsics that perform designated tasks. Table 3-1 “Accessing Files” through Table 3-18 “Controlling Asynchronous Devices” describe the general task, a subtask to the general task, and the intrinsic associated with it. The general task is, in most cases, the title of a programmer's guide and the subtasks correlate to chapters within that programmer's guide. For information about the intrinsic specifically, refer to the later chapters of this manual. For information about the use of an intrinsic, refer to the specified programmer's guide.
