Enterprise COBOL for z/OS, Version 4.1, Compiler and Runtime Migration Guide


Moving from the OS/VS COBOL run time

This chapter provides detailed information about running OS/VS COBOL programs with Language Environment. It includes information on:
Additional information about moving your run time to Language Environment is included in:

Each section in this chapter indicates if it is applicable to existing OS/VS COBOL programs compiled with the RES compiler option, NORES compiler option (including whether the programs are link-edited with Language Environment), and for applications running on CICS, by listing one or more of the following:

RES
An application comprised of programs compiled with RES.
NORES
An application comprised of programs compiled with NORES. The NORES programs have not been link-edited with Language Environment.

OR

An application comprised of OS/VS COBOL programs compiled with NORES that is link-edited with Language Environment, but does not contain any of the following:
  • A VS COBOL II program
  • A COBOL/370 program
  • A COBOL for MVS & VM program
  • A COBOL for OS/390 & VM program
  • An Enterprise COBOL program
  • The IGZCBSN or IGZCBSO bootstrap routine
CICS
An application that runs under CICS.
NORES linked
An application comprised of programs compiled with NORES. The NORES programs have been link-edited with Language Environment and now behave as if they were RES. The application does contain at least one of the following:
  • A VS COBOL II program
  • A COBOL/370 program
  • A COBOL for MVS & VM program
  • A COBOL for OS/390 & VM program
  • An Enterprise COBOL program
  • The IGZCBSN or IGZCBSO bootstrap routine
Note: For multiple load module applications, if the first executed load module contains one of the above, the application will behave as if it were RES.
