          Figure 8-2.  Log Record Heading Format 

Each log record begins with a standard header and ends with
identification information.  The header comprises the first 16 bytes of
the record.  The format of the heading is the same for all log records.
(See Figure 8-2.)

The following definitions describe the components of the log record
heading.  In Figure 8-2, the numbers in parentheses indicate the number
of half words in each field; the numbers within the fields indicate the
starting bit for each subfield.

Record Type           Defines the record as one of the types described
                      above.

Record Length         Defines the number of bytes that the record
                      contains.

PIN                   Process identification number (PIN) of the process
                      that is making the entry.

Time Stamp            The date and time, in the following format:

                      Word 1:  Output from CALENDAR intrinsic

                      Words 2-3:  Output from CLOCK intrinsic

Job Type              Type of main process being run, where bits 0 and 1
                      have the following meaning:

                      (00) System

                      (01) Session

                      (10) Job

Job Number            A number defining the job or session under which
                      the log record was output.  If this last word is 0,
                      this means that the record is system-related, not
                      output for a user.
