Cause . . . . . : RPG specifies MLTRCD(*YES) in the UFCB (User-File-Control Block). Records are passed between RPG and data management in blocks. Positions 241 through the end of the INFDS (File-Information-Data Structure) are updated only when a block of records is read or written.
Recovery . . . : If this information is needed after each read or write of a record, specify the OVRDBF command for the file with SEQONLY(*NO).
