Header/self-defining section

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	SMF23LEN	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	SMF23SEG	2	binary	Segment descriptor (see record length field).
4	4	SMF23FLG	1	binary	System indicator: Bit Meaning when set 0-2 Reserved 3-6 Version indicators (See Standard SMF record header for details.) 7 Reserved.
5	5	SMF23RTY	1	binary	Record type 23 (X'17').
6	6	SMF23TME	4	binary	Time since midnight, in hundredths of a second, when the record was moved to the SMF buffer.
10	A	SMF23DTE	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.
