Data interpreter for RBOC bills

A computer-implemented method to more correctly bill a customer of a reseller of telephone service, based on wholesale billing data of a telephone company and the reseller's internal billing information regarding charges of the telephone service for the customer, the method comprising:

• accessing a part of the wholesale billing data to identify, based on a record from the telephone company, a portion of the accessed wholesale billing data for subsequent data manipulation;
• generating tabulated data from the identified portion of the accessed wholesale billing data, through data manipulation;
• and
• comparing the tabulated data with the reseller's internal billing information so as to more correctly bill the customer;
• wherein the tabulated data is not in EBCDIC data format and the wholesale billing data is in EBCDIC data format;
• wherein the wholesale billing data can have millions of characters, with thousands of identifiers;
• wherein the EBCDIC data format is a mainframe computer data format;
• wherein only a part of the wholesale billing data is accessed and manipulated at a time to conserve memory space;
• and
• wherein less than 20% of the data accessed can be identified for subsequent data manipulation so that additional memory space is conserved.
