and floppy disk drives the memory 10 provides a number of locations which are accessible by the processor 9 within the locations are stored hexadecimal numbers the numbers will be instructions for controlling the operation of the processor 9 that is to say they are program and data the way in which the memory is arranged is illustrated in fig3 it can be seen from fig3 that the memory 10 has six divisions 11 12 13 14 15 division 11 holds the above mentioned program division 12 is allocated for holding radio type and personality data division 13 holds a generic manual this is in the form of a file which can be read in blocks the blocks corresponding to text which is eventually used to provide the specific manual this manual is generic in the sense that it can serve as the basis for manuals for any configuration of the transceiver 2 division 14 is allocated for holding the specific manual as it is assembled in a process which will be described later at the end of the process it will store the complete specific manual for the transceiver 2 ready for copying to disk or for printing as a hard copy manual division 15 stores blocks of text copied from the generic manual held in division 13 during the processing step which will be described later division 16 stores information on options which have been enabled on the transceiver 2 these options are obtained from.
