Header/Self-defining Section

This section contains the common SMF record headers fields and the triplet fields (offset/length/number) that locate the other sections on the record.

This triplet information should be checked prior to accessing a section of the record. All three fields being non-zero mean that the section exists on the record; conversely any of the fields being zero indicates that the section does not exist on the record. The ‘number’ triplet field is the primary indication of the existence of the field.

Offsets Name Length Format Description
0 0 SMF24LEN 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 SMF24SEG 2 binary Segment descriptor (see record length field).
