IBM SC33-1683-02 - Manual (Page 676)

Note: The format of caller data in journal records written by file control in RLS
mode is identical to that in journal records written by file control in non-RLS
mode except for FLJB_TUR_BITS where a value of X'80' indicates
RLS-access.
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 69.
FEPI prefix data
Each FEPI journal record contains a prefix area that allows you to identify the FEPI
conversation for which the data was journaled. This prefix area lies in the position
of the prefix area in the API user header. Its format is shown in Figure 70 on
page 645.
