Chapter 1 Introduction This manual describes how to change programs written in COBOL II/V into HP COBOL II/XL programs. COBOL II/V runs on MPE V based 3000 systems and on MPE XL systems in compatibility mode. HP COBOL II/XL runs on the MPE XL based 3000 systems and on MPE XL systems in compatibility mode. Few differences exist between COBOL II/V and HP COBOL II/XL. Most of the differences in the language relate to machine and operating system dependencies. All differences are outlined in this manual. Chapter 2 describes the new features of COBOL II/XL and briefly presents the obsolete and changed features. Complete information on how to change COBOL II/V programs to make them compatible with COBOL II/XL is provided in Chapter 3. Programmers who adhere to ANSI COBOL Standards X3.23-1974 or 1985 and do not rely on HP extensions or machine-dependent features should have few, if any, changes to make in migrating their programs from COBOL II/V to COBOL II/XL. You can run COBOL II/V programs on MPE XL based computers in compatibility mode. Compatibility mode allows object code from a COBOL II/V program to run on an MPE XL system after a simple STORE/RESTORE operation. However, to take full advantage of the HP precision architecture, you should recompile the application using the COBOL II/XL compiler.
