Changing OS/VS COBOL programs

Although the OS/VS COBOL compiler is no longer supported, the programs that were generated by it are supported if they are running under Language Environment® and not interoperating with Enterprise COBOL V5 or V6 programs. Once you have migrated your runtime library to Language Environment, you can run your source code through a source conversion tool, such as the COBOL and CICS® Conversion Aid (CCCA) and then compile using the Enterprise COBOL compiler.

For more information about CCCA, see Conversion tools for source programs.
