The SMF block header
This block describes the system creating the output. Its format is shown in
Figure 82.
Note: CICS sets only the subsystem-related bits of the operating system indicator
flag byte in the SMF header (SMFH_LG). SMF sets the remainder of the
byte according to the operating system level and other factors. For an
explanation of the setting of the other bits, refer to the
OS/390 MVS System
Management Facilities (SMF)
manual.
