To aid in moving your runtime library to Language Environment®, you can find information on how to run existing VS COBOL II and OS/VS COBOL load modules under Language Environment, including link-edit requirements for support and recommended runtime options for compatible behavior in the Enterprise COBOL V4.2 Compiler and Runtime Migration Guide at http://publibfp.dhe.ibm.com/epubs/pdf/igy3mg50.pdf.

To aid in moving from your older COBOL compiler to Enterprise COBOL, this information provides descriptions of the language differences between older COBOL compilers and Enterprise COBOL and describes the IBM® conversion tools available to aid in converting your source programs to Enterprise COBOL programs. It also describes other differences that might require changes in your application development process in order to use Enterprise COBOL.
