Abstract
In an electronic postage meter having a program for updating accounting memory in a printing cycle, flags are set in the accounting memory at each of a plurality of steps during the updating of the accounting registers, the flags providing an indication in a power-up cycle following a loss of power, of the steps necessary, if any, to complete an accounting that had not been completed prior to the previous loss of operating power.
