Assume an adabas database has been mapped with DDMS. viz IDENTIFICATION-TABLE & IDENTIFICATION-TABLE-EXP The difference between two DDMS is IDENTIFICATION-TABLE-EXP created with IDENT-NAME as (A6) whereas IDENTIFICATION-TABLE with (A4). A batch program is updating the database with IDENTIFICATION-TABLE-EXP. Values are as below. IDENT-ID IDENT-NAME IDENT-AGE ----------------------------- 1234 AAAAbb 23 2345 ACDBCD 13 3456 ADSBbb 25 4567 DADSbb 15 5678 EDSCbb 20 READ IDENTIFICATION-TABLE BY SUPER-ID-NAME-AGE STARTING FROM '1234' DISPLAY IDENT-ID IDENT-NAME IDENT-AGE LOOP How many records will be displayed in the output? * small case b stands for space

E Correct answer
Explanation

When a record layout or DDM length mismatch occurs where the database contains data longer than the program's DDM definition (A4 vs A6), updating or reading may lead to mismatch behavior, but in Adabas/Natural, changing field length specifications or updating with mismatch formats can cause runtime errors (such as NAT3009 or type conflicts) during execution, leading to abnormal termination.
