•Trying to input a data item that takes up more bytes than are currently available in memory area (b) causes the message “Data Full” to appear on the display. If this happens, you can press <1to select “EditOFF.” Though this will allow you to input more statistical data items (and free up memory area (b) for program storage), it also deletes the data items that are currently stored in memory areas (a) and (b). Also, the data items you input after pressing <1 will not be saved. This means you will not be able to view or edit individual data items after you input them.
•To input new statistical data when editing is turned off (EditOFF), press A B1(Scl) <to delete statistical data currently stored in memory and turn editing on (EditON). You will be able to input statistical data into the statistical data area (a) and the program memory area (b) that does not contain program data. You can also delete program data you no longer need to free up space for further statistical data input.
kPrograms
•Each function you input into program memory takes up either one byte or two bytes of memory, as shown below.
••Pressing e or r while a program is on the display causes the cursor to jump one byte in the direction indicated by the arrow.
•Inputting the first program while there are no other programs in memory causes 24 bytes of memory to be reserved automatically as a program management area (area (c) on page 44).
•A newly input program is stored in free space (space not currently being used for program storage or statistical data storage) that is available in the program memory area (area (b) on page 44). All 360 bytes of the program memory area are available for program storage when there is no statistical data stored in the program memory area.
