All AS/400 Tip Categories / AS/400 Programming / Getting the relative record number (RRN)


Question:

Does anyone know how to get the relative record number?


Answer(s):



Which RRN, the First on the Display?
   FDISPLAY CF  E                    WORKSTN
   F                                        RRN   KSFILE SFLRCD
   F                                              KINFDS ###DSP
   I###DSP      DS
   I                                     *STATUS  DSPSTS
   I                                    B 378 3790@SFLRN
@SFLRN will have the RRN for the first record on the subfile that is displayed, that is the number of the record that is first on the current subfile 'Page'. If you want the RRN of the last record read with a READC, that's RRN.




IFDS. An answer as short and indescriptive as the question.




Here is a part of the I/O-feedback area for RPG-IV. There should be no problems to translate it to RPG-III.

     FFILE00    UF   F 4096        DISK    USROPN
     F                                     INFSR(*PSSR)
     F                                     INFDS(File#00)
     F                                     COMMIT(CommitLVL)
‚     *
     DFile#00          DS
     D F0Status               11     15S 0
     D F0File                 83     92A
     D F0Library              93    102A
     D F0Member              129    138A
     D F0NbrOfKey            387    388B 0
     D F0RcdNbr              397    400B 0





Look for "IO feedback" subject in whatever you are trying to work with... I's all there.
