Creating a source file without DDS
When you create a source physical file without using DDS, but by specifying the record length (RCDLEN parameter) on the Create Source Physical File (CRTSRCPF) command, the source created contains three fields: SRCSEQ, SRCDAT, and SRCDTA.
The record length must include 12 characters for sequence number and date-of-last-change fields so that the length of the data portion of the record equals the record length minus 12. The data portion of the record can be defined to contain more than one field (each of which must be character or zoned decimal). If you want to define the data portion of the record as containing more than one field, you must define the fields using DDS.
A record format that consists of the following three fields is automatically used for a source physical file that is created with the CRTSRCPF command.
| Field | Name | Data type and length | Description |
|---|---|---|---|
| 1 | SRCSEQ | Zoned decimal, 6 digits, 2 decimal positions | Sequence number for record |
| 2 | SRCDAT | Zoned decimal, 6 digits, no decimal positions | Date of last update of record |
| 3 | SRCDTA | Character, any length | Data portion of the record (text) |
