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 letter b stands for space

E Correct answer
Explanation

The data was stored using IDENTIFICATION-TABLE-EXP with IDENT-NAME as A6 (6 bytes), but the READ uses IDENTIFICATION-TABLE where IDENT-NAME is defined as A4 (4 bytes). This field length mismatch causes a runtime error because the READ operation cannot properly interpret the 6-byte data using a 4-byte field definition, resulting in abnormal program termination.
