Re: Performance - RPG vs Cobol

It could use SQL, it could use RLA, depends on how you configure the model. I have only used RLA. There are several patterns that deal with subfiles, and several that deal with individual records. You can choose whether it loads the subfile one page at a time, or the entire subfile.
