The following records are initialized by using the System Test
Compiler to build a pilot tape. The pilot tape is subsequently loaded
onto the system files by the System Data Loader. For more information
about the System Test Compiler, see TPF
Operations.
Fixed-file records are written to their allocated address and are
retrieved by Message Switching programs by using File Address
Compute.
Core Resident records are loaded into the Global Area by the
Application Core Load and Restart Program at system restart time. These
records are then accessed by Message Switching programs by using the
appropriate tag in the Message Switching Global Field.
