The document discusses load-all subfiles in RPG. It explains that in a load-all subfile, all records are written to the subfile buffer at once before being loaded from the buffer. It notes that the subfile size (SFLSIZ) should be at least 1 greater than the page size (SFLPAG) and if more records are written than SFLSIZ, it will extend to a maximum of 9999. It also explains that the current page number can be passed to the SFLRCDNBR field to avoid the display always returning to the first page when enter is pressed.

 Load-All Subfile

In Load-All subfile all the records are written to the subfile buffer at once and then the data in the subfile
loaded from the buffer.

In this case SFLSIZ should be at-least 1 greater than the SFLPAG.

If we are writing more records in the subfile buffer than the SFLSIZ declared and SFLSIZ<9999, then the
SFLSIZ is extended to accommodate all records till the size of 9999. 9999 is the buffer limit.

In this case PAGEUP AND PAGEDOWN is taken care by system. SFLPAG should be less than SFLSIZ.

In load-All subfile if we do PAGEDOWN and then press ENTER on the page, by-default ENTER bring the
display screen to the very first page irrespective of the current page number. To avoid this situation, we use
file information data structure to get the current page RRN number and pass it to the SFLRCDNBR hidden
field defined in the display file DDS.
