A method and apparatus are described for controlling access of a user of a postal value computing system to the computation of special fees. A directory memory stores a special fee control byte which is combined with a rate fee screen byte that is generated by the system to represent the special fee computations requested in response to actuation of the keyboard. The combining of the bytes employs a bit for bit AND operation with the result stored as a modified rate screen byte for use in the subsequent special fee computations. Access may then be granted or denied, depending upon the special fee control byte.

A method for controlling access to the computation of special fees so as to limit access to selected allowable special fee computations with a postage value computing system having a program operated processor, a rate memory to store postage rate information, a directory memory to store vectors to direct the program in the processor to rate charts and special fee computations to which access is requested by actuations of a keyboard comprising the steps of: storing in the system a rate fee screen byte representative of special fee computations permitted with a particular mailing class; recalling a special fee control byte representative of special fee computations as to which access is allowable; combining the rate fee screen byte with the special fee control byte to form a modified rate fee screen byte; and computing special fees in accordance with the modified rate fee screen byte.
