Command codes to manage subset pointers in DEDBs

With DEDBs, you can set and use up to eight subset pointers for each direct dependent segment type in the database description (DBD).

You must also define in the PSB, using the SENSEG statement, which subset pointers your program will use. You can then use subset pointers from within the application program together with certain command codes. EXEC DLI keywords and corresponding DL/I CALL command codes tells you which subset pointers you can use with which command codes.
