This was rather disappointing as RPGLE is over 21 years old , free format calculations 14 years old, even free format definitions RPG is in its third year.

If you need to read records that were loaded due to a page down key after you chained to the subfile, you will need to process those records later. Personally, I have found this technique much easier than using subfile keywords. The code is simple and easy to maintain.
