Abstract of the Disclosure A portable, handheld data entry device is disclosed which includes a solid state memory for providing bulk storage of data entered through a keyboard, scanning wand, or other data entry means. A microprocessor controls the various operations performed by the unit, including storage of data in memory and memory management. During operation, the memory is defined to include a number of independent data storage sections or partitions. Each partition includes a data block containing related data which has keen entered into the partition. All re- maining free memory space is located in a single partition, adjacent to the data block of that partition. Data may thus be added to that partition by entry of the data into the free memory space adjacent to the data block. When data is to be entered into a different partition, the data blocks are relocated in memory so that the free memory space is instead within that different partition, adja- cent to its data block. The size of each partition is therefore not fixed, but varies with the data entered. me data entry device also incorporates methods of sending selected partition in any arbitrary order to an external device, and of editing the partition data block by inserting or deleting variable-length data records.
