Chapter 10 Portability Issues This chapter provides guidelines on developing applications that are portable at either source code or intermediate code level between this COBOL system and equivalent systems on other environments. These systems are principally COBOL for DOS and COBOL for UNIX respectively. For brevity, this chapter refers to DOS to mean DOS, Windows, and OS/2. Portability is achieved using the INTLEVEL Compiler directive. The guidelines in this chapter describe programming methods that enable you to make best use of this directive in creating portable applications. This chapter assumes a working knowledge of the DOS and UNIX operating systems and of this COBOL system and its equivalents on these operating systems.
