Micro Focus has its own file handler called Micro Focus ISAM that it has developed and enhanced for over two decades to provide file processing support for all Micro Focus COBOL based applications. Within version 8.1 of Open PL/I we have therefore switched to using this core technology from Micro Focus rather than relying on the 3 rd party file handler for Indexed files that was utilised originally within Open PL/I.
This will enable all Micro Focus to provide ongoing support for all file processing requirements of our Open PL/I customers from a single technology shared with all Micro Focus COBOL customers but it does require data to be unloaded from original files formats and loaded into new Micro Focus file formats. The following document gives guidance about how to go about this transition process.
