following formula.
File number = File register number / 10000
Record number = File register number % 10000 - 1
The maximum amount of access points depends on the allocation points of the file
registers.

The file and record numbers associated with cache registers are calculated using the
following formula.
File number = Cache register number / 10000 + 100
File number = Cache register number % 10000 - 1
The maximum amount of access points depends on the allocation points of the file
registers.
