You can use the source entry utility (SEU) to enter and change source in a source file. SEU is part of IBM® WebSphere® Development Studio for iSeries™.
If you use SEU to enter source in a database file, SEU adds the sequence number and date fields to each source record.
If you use SEU to update a source file, you can add records between existing records. For example, if you add a record between records 0003.00 and 0004.00, the sequence number of the added record can be 0003.01. SEU will automatically arrange the newly added statements in this way.
When records are first placed in a source file, the date field is all zoned
decimal zeros (unless DDS is used with the DFT keyword specified). If you
use SEU, the date field changes in a record when you change the record. See
the ADTS for AS/400: Source Entry Utility manual on the V5R1 Supplemental Manuals
Web site for information about
how to update database source files.
