This section contains the common SMF record headers fields and the triplet fields (offset/length/number), if applicable, that locate the other sections on the record.
| Offsets | Name | Length | Format | Description | |
|---|---|---|---|---|---|
| 0 | 0 | SMF79LEN | 2 | binary | Record length. This field and the next field (total of four bytes) form the RDW (record descriptor word). See Standard SMF record header for a detailed description. |
| 2 | 2 | SMF79SEG | 2 | binary | Segment descriptor (see record length field). |
| 4 | 4 | SMG79FLG | 1 | binary | System indicator:
*See Standard SMF record header for a detailed description. |
| 5 | 5 | SMF79RTY | 1 | binary | Record type 79 (X'4F'). |
| 6 | 6 | SMF79TME | 4 | binary | Time since midnight, in hundredths of a second, when the record was moved into the SMF buffer. |
| 10 | A | SMF79DTE | 4 | packed | Date when the record was moved into the SMF buffer, in the form 0cyydddF. See Standard SMF record header for a detailed description. |
| 14 | E | SMF79SID | 4 | EBCDIC | System identification (from the SMFPRMxx SID parameter). |
| 18 | 12 | SMF79SSI | 4 | EBCDIC | Sub-system identification (‘RMF’). |
| 22 | 16 | SMF79STY | 2 | binary | Record subtype. |
