File description specifications

 

iSeries™ users can access remote VSAM data sets with iSeries System/36-Compatible RPG II or ILE RPG programming language.

However, not all ILE RPG processing methods selected by the file description specifications can access remote VSAM data sets. Refer to the following tables to determine which file description specifications to use. If a file description specification other than what appears in these tables is used, CICS/DDM rejects the request for opening the file.
