Hi All,
Could you please tell me the difference between READ LOGICAL and FIND?
I have Confusion with the read of inverted list in both the stmt.
Thanks,

Thatâs also why READ returns the same record multiple times when reading by a multiple descriptor with more than one match, while FIND only returns a given record once.
FIND over the already said doesnât returns ISNs of Zero suppressed descriptors if you would have records with an empty descriptorvalue within your searchcriteria. (Based on ADABAS-C)
READ wouldnât either
:oops: i didnât know that read logical also use descriptortables
If you donât have any non-null-suppressed descriptors, a READ PHYSICAL is the only way to get ALL records
Or a CALL âADABASâ
NATURAL âinternallyâ issues L1, L2, L3 ⌠calls as well, so you donât get anything different with a âdirectâ call, youâre just using a more âfriendly nameâ for the command
Sorry for disturbing: What about READ BY ISN?
This only work for files with not-null-suppressed ISNs !
Just joking, yourâre right, of course thatâs the second âonlyâ method to read all records independent of descriptors
Thanks a lot for your valuable time.
