You can run existing load modules under Language Environment and receive the same results as with pre-Language Environment libraries. For important compatibility information, see Running existing applications under Language Environment.
For information on moving applications that are running under the OS/VS COBOL run time, see Moving from the OS/VS COBOL run time.
For information on moving applications that are running under the VS COBOL II run time, see Moving from the VS COBOL II run time. (Because you might have been running OS/VS COBOL programs under the VS COBOL II run time, this chapter duplicates the information from Chapter 5 that is applicable to OS/VS COBOL programs running under the VS COBOL II run time.)
Link-editing programs with Language Environment can result in different behavior, see Link-editing applications with Language Environment for details.
