Abstract

The figure shows two flow charts. The flow chart on the left shows the method steps required to compact a large number of long financial account numbers into the same number of shorter records, containing the high-order quotient bits Q of the account number and the status of the account. The low-order remainder bits R are used to generate an R table, which points to the first entry in the block of records storing Q and status for all account numbers having the same low-order bit pattern. A divisor of 2048 is shown by way of example.

Account Number Compaction for File Storage

The figure shows two flow charts. The flow chart on the left shows the method steps required to compact a large number of long financial account numbers into the same number of shorter records, containing the high-order quotient bits Q of the account number and the status of the account. The low- order remainder bits R are used to generate an R table, which points to the first entry in the block of records storing Q and status for all account numbers having the same low-order bit pattern. A divisor of 2048 is shown by way of example.

The flow chart on the right shows the method steps required to inquire into the status of an account stored by compacted account number. The status of the account such as overdrawn, ID card stolen, etc., is gated back to the inquiring station from the block of records identified by the low-order bits or R value of the received account number, and from the record having a Q value which is equal to the Q value of the received account number.
