RPGLE DDS Subfile out of 9999 records limit

Hi,

As you know that IBM restricted to the 9,999 records limit when load a
subfile, and we can just load one page at a time to not limited by the
number of records.

But I have a situation that need to load all data (almost 30, 000 records)
into subfiles, and allow user to do page down, page up to select/change
multiple records. I can do the page down & page up, but how can I get my
selected data 'cause the original SFLRCDNBR can only up to 9999 ?

Any hints, suggestions or sample codes would be really appreciated!
