Abstract: A method and apparatus are described for directing operators to a plurality of locations to gather data in a portable data collection apparatus. The method provides for data compression for efficient utilization of solid state memory in the apparatus and allows for the data describing the multiple accounts to be in variable numbers of fields and field lengths. The apparatus keyboard provides for sequential and random accessing of the accounts for data entry and display, and for listings of the different types of areas to be visited. Additionally, it provides for searching missed accounts and for locating a desired account in the record. Capabilities are provided for storing new accounts and identifying their location in the record. Specifically, the application for utility meter reading is disclosed, in which, data read from a plurality of utility meters is stored in the apparatus by the meter reader, and later transmitted to a data processor for billing purposes.
