What are the uses of DBKey?

- DBKEYs are saved temporarily within a program for direct database accessibility.

- DBKEYs are used to retrieve the immediate previous record after executing many intervening database operations.

- DBKEYs of the removed records are reused. IDMS commands UNLOAD or RELOAD changes all the DBKEYs.

- Hence, incorrect results may occur, when DBKEYs are persisted outside of the program.

- DBKEYs might be accessible in temporary storage until the end of task performance is done, in on-line pseudo-conversational programming.
