Deployment of COBOL applications in an execution-only environment requires the COBOL Runtime Environment for AIX 5.1 product. It is a separately orderable runtime product for execution of developed IBM COBOL applications. With this orderable COBOL Runtime Environment, the redistribution of runtime libraries in the COBOL for AIX product is no longer required or permitted.
