CLF provides a common, consistent interface to your System i resources.
The PowerCL: CL for Files (CLF) product maximizes the productivity of your operators and programmers. CLF supports the use of System i files directly from CL applications. With a rich set of CL commands CLF allows your CL developers to directly work with file types such as database, display, and printer. System operations and application developers can experience significant productivity enhancements as they no longer need to work with multiple languages in order to use the flexibility of CL and the database support of high level languages such as RPG, COBOL, and C. CLF provides a superset of the file support found in these other high level languages, and this superset is accessible entirely through CLF provided command interfaces.
