Message switching core tables are loaded from 1055 byte file records. The amount of core required per table will determine how many file records are needed. Because of the programming techniques used in handling these core tables, the tables are divided into three categories.
These message switching core tables are composed from only one
file record because of built-in limits.

This group of core table records are loaded with headers dropped from all
file records but the first record of that core table. The reason for
this is that all data must be accessed from adjacent core locations.
Therefore, the second record must be loaded consecutively into core after the
first, etc.

The following core tables have provisions to skip header entries of other
than the first file record comprising that core table. The file records
must, however, be loaded consecutively one after the other.
