Terminal control prefix data

CICS terminal control (TC) writes journal records to track the messages it issues.
Each TC journal record contains a prefix area, which lies in the position of the prefix
area in the API user header. For LU6.1-related records only, the prefix area
contains the VTAM physical sequence numbers at syncpoint time; for all other TC
journal records, it contains binary zeros. The format of the TC prefix area is shown
in Figure 87 on page 727.
