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.
