Answer :
Explanation :
Key Fields - (PROCOPT=K) - Used to sequence the database and can't be changed - It is the field within a segment, used to identify the occurrence of the segment - Used to maintain the IMS segments in ascending sequence. Search Fields - (PROCOPT=G) - Used to search for a segment, without the segment being sequenced on that field - A segment need not have a key or search field. Both types of fields can be used to search the database.
