Ü  SFLSCROLL

 

·         This display file keyword is used to store the RRN value of the first record of the subfile after the PAGE UP or PAGE DOWN activity is done.

·         When we do PAGE UP/PAGE DOWN and then press ENTER, the current RRN value of the top record of subfile is returned to the program.
