HANDLING PRECAUTIONS @ This unit is composed of precision electronic components and should never be disassembled. Da not drop it or otherwise subject it to sudden impacts or sudden temperature changes. Be especially careful to avoid storing the unit or leaving it in areas exposed to high temperature, humidity or large amounts of dust. When exposed to low temperatures, the unit will require more time to display answers and may even fail to operate.

W Number of input/output digits and computation digits ®The allowable input/output rigger (number of digits) of this unit is 10 digits for & mantissa and 2 digits for an exponent. Computations, however, are internally performed with a range of 13 digits for a mantissa and 2 digits for an exponent. Ex.

The graph function! of this unit makes it possible to produce a wide variety of function and statistical graphs quickly and easily dot display. (Upmost and leftmost lines are not used.) Besides the built-in function graphs, a generous selection of functions can also be input for graphic representation. Graph commands can be used manually or in programs, but here all examples will be entered around manual operations.
W Overwriting built-in function graphs Two or more different built-in function graphs can be written together op the same display. Since the range for the first graph is automatically set, all subsequent graphs on the same display are produced according to the range of the first.graph. The first graph is produced by using the previously mentioned operation (s [function key] (B} Subsequent graphs are produced using the variable X in the operation s [function key] e B8 [Exe] (B : B key).

After the trace function is executed and the text Display is brought up using the (&1l key, pressing (E&] causes the next graph o appear and the coordinate value to clear.

4-1 WHAT IS A PROGRAM? This unit has a built-in program feature Thai facilitates repeat compute. sons. The program feature is used for the consecutive execution of for. mauls in the same way as the “multi statement” feature is used in manual computations. Programs will be discussed here with the ald of illustrative examples, EXAMPLE: Find the surface ares and volume of a regular tetrahedron when the length of one side is given.
When et (2] are pressed, the system mode changes to the WRT mods, Then, the number of remaining steps {see page 106)is indicated. The number of remaining steps is decreased when programs are input or when memories are expanded. If no programs have been input and the number of memories equals 26 {the number of memories at initialization), the number of usable steps should equal 4,006. The larger figures located below indicate the program areas (see page 108).

4-4 COUNTING THE NUMBER OF STEPS The program capacity of this unit consists of a total of 4,006 steps. The number of steps indicates the amount of storage space available for programs, and it will decrease as programs are input. The number of remaining steps will also be decreased when steps are converted to memories. (See page 24).
4-5 PROGRAM AREAS AND COMPUTATION MODES This unit contains a total of 10 program areas {P0 through P9} for the stir. age of programs. These program areas are all utilized in the same man. ner, and 10 independent programs can be input. One main program {main routine) and a number of secondary programs {subroutines) can also be stored. The total number of steps available for storage in program areas PO through P8 is 4,006 maximum.

If this is simply left the way it is, however, the volume will not be display, ed and execution will move immediately to the input of one side at xg?; beginning. To prevent this situation, insert a display command () front of the “Goth 1", " The complete program with the unconditional jump added should look like this: Wbl VU2, 102, Goth, 1 25 steps Now let's ry executing this program.

I this program, first 10 is stored in memory A, and 0 is stored in memory €. Memory A is used as the “counter” and countdown is performed the specified number of times by the Dsz command. Memory G is used to store the sum of the inputs, and so first must be cleared by inputting a 0.
Subroutine e, > P3 Main routine Prof 4 8 Levi 1 Levi 2 Level 3 Level 4 The subroutine command is “Prof” followed by a number from 0 through 9 which indicates the program area. Example: Prof 0 to program area 0 Rag 2 -4, Jump to program area 2 After the jump is performed using the Prof command, execution continues from the beginning of the program stored in the specified program area.
Computation of the volumes is also performed in a similar manner. After a jump is made to P8 for computation, execution returns to the main routines. In PO, the program ends after the volume of the tetrahedron i displayed. In P1, however, the result computed in P8 is divided by four to obtain the volume of the tetrahedron. By using subroutines in this man. ner, steps can be shortened and programs become neat and easy to read. The following illustration shows the flow of the program just presented.
4-8 ARRAY-TYPE MEMORIES M Using array-type memories Up to this point all of the memories used have been referred to by single alphabetic characters such With the array-type memory introduced here, a memory name (one alphabetic character from A through Z) is appended with a subscript such as [tor [2].
The following shows: a case in which array-type memories overlap wiy standard format memories. This situation should always be avoided. Example: Store the numeric values from 1 through 5 in memories A1) through A{5] respectively. ALT C, :.Goth, 1, ©, 1,1, 47102 ] 441031 4 4.
Y Example program 2 The same memories are used as in Example 1, but two types of memory names are used and the x and p dale kept separate.
It messages are included as shown here, the display is as follows; goings longer than 16 characters are displayed in two lines. When {Assuming that the program is stored in P1) Alphabetic characters are displayed at the end of the bottom line, the :nme display shifts upwards and the uppermost line disappears from the (Pisa] 1 [84E} 10(8€) ¥751 0 123+45 168. 852-87 Messages are also convenient when displaying result in program com. 765 mutations. . P Example: 1028.
4-10 USING THE GRAPH FUNCTION IN PROGRAMS Using the graph function within programs makes it possible to graphic. ly represent long, complex equations and to overwrite graphs repeatedly, All graph commands {except the trace function) can be included in pro. grams. Range values can also be written into the program. Generally, manual graph operations can be used in programs without modification. Ex. 1) Graphically determine the number of solutions {real rots} that satiety both of the following two equations.
PROGRAM LIBRARY <{Prior to use> # Always check the number of remaining steps before attempting to store programs. #The library is divided into two pairs: a calculation section and a graph section. The calculation section shows only answers, while the graph section shows whole displays. ®To make programs in the graph section easier to follow, * is used to indicate carriage returns. The [BE] key should be pressed wherever « appears (« does not appear on the display).
