A module-definition file contains one or more “module statements.” Each module statement defines an attribute of the executable file, such as its name, the attributes of program segments, and the number and names of exported and imported functions and data. Table A.1 summarizes the purpose of the module statements and shows the order in which they are discussed in this chapter.
