Byte Position Bytes Field Name Description<br />

Chapter 4. Record Formats<br />

Start of Document (SOD)<br />

17-24 8 Job Identifier This field is used only if security is enabled. It is an 8-byte Job<br />

Identifier and must be the same as the Job Identifier field in the<br />

JC2 record.<br />

The Starting Font Number, Starting ILS, And Starting Fixed File Number<br />

fields are optional. These 3 fields are either all present or all not present.<br />

If the 3 fields are not used for a non-security SOD record (control code<br />

04), the record ends at byte position 12.<br />

For a security SDC (control code 11), the 3 fields must be present<br />

because the Job Identifier field is required.<br />

If the Starting Font Number and Starting ILS fields are present, the<br />

starting font is set and the Y line spacing is set to the value in the ILS field.<br />

The other three spacing values are set to 0.<br />

If the Starting Font Number and Starting ILS fields are not present, the<br />

starting font is set to that specified as the default font in the FAR or JCR<br />

record. If there is no FAR or JCR, the font for the current RIP with the<br />

lowest font ID is used. If the starting font was defined by SFD or FDR, the<br />

ILS value in that record is used for the Y line spacing value and the other<br />

three spacing values are set to 0. If the font was defined by SFM or FDM,<br />

the ILS is set to 0, along with the other three spacing values.<br />

If the Starting Fixed File Number field is not present, this parameter is set<br />

to fixed file 0.<br />

All fixed file pointers are reset to the beginning of their respective fixed<br />

files at the start of a document.<br />

The logical function is set to 01 (“or”) at the start of each document.<br />
