4-4 GRUNTING THE NUMBER OF STEPS The program capacity of this unit consists of a total of 1446 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 storage of programs. These program areas are all utilized in the same manner, 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 P9 is 1446 maximum.
M Cautions concerning the computation modes All key operations available in each computation mode can be stored as programs, but, depending on the computation mode, certain commands or functions cannot be used. Base-n mode « Function computations cannot be performed. » Units of angular measurement cannot be specified. « Ali program commands can be used. » Be sure to include a “4" at the final result output to return to the previous computation mode when a program execution is terminated.

Add “Goth 1" to the end of the program, and add “Lbl 1" to the beginning of the program as the branch destination. If this Is simply left the way it is, however, the volume will not be displayed and execution will move immediately to the input of one side at the beginning.
The is displayed when (7] (0 are pressed. If the condition is true, execution advances to the statement following =. if the condition is not true, the statement following = is skipped and execution jumps to the statement following the next true Left Relational Right Sta Testate- side operator side men 4 men I not true A statement is a computation formula {sin AX S, etc.) or a program command {Goth, Prof, etc), and everything up to the next regarded as one statement.
in this program, first 10 is stored in memory A, and 0 is stored in memory C. Memory A is used as the “counter” and countdown is performed the specified number of times by the Dsz command. Memory C is used to store the sum of the inputs, and so first must be cleared by inputting a 0.
. : Subroutine Main routing £>P3 _Prof 8 9 Tevet 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 ~Jump to program area ¢ Prof 2 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 routing. In PO, the program ends after the volume of the tetrahedron is 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 manner, steps can be shortened and programs become neat and easy to read. .
4-8 ARRAY-TYPE MEMORIES M Using array-type memories Up 1o 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 [1] or [2].
| | The following shows a case in which may-lype memories overlap with standard format memories. This situation should always be avoided. Example: Store the numeric values from 1 through § in memories A1) through Al5] respectively, ,Lbl 1, ¢ LACY I, Dsz,C, &, Goth, 1, 1, ALLAHABAD 4403, als] In this program, the values 1 through 5 are stored in the array-type memories A[1] through A[S], and memory C is used as a counter memory.
Example program 2 The same memories are used as in Example 1, but two types of memory names are used and the x and y data kept separate. 1, A I, Dem LAL L, Isz, 6,=> Goth, 2, !, Goth, | Lbl, 2, 1, 1,5,~ Gog, 5, .

4-10 USING THE GRAPH FUNCTION IN PROGRAMS Using the graph function within programs makes it possible to graphically represent long, complex equations and to overwrite graphs repeatedly. All graph commands {except the trace function} can be included in programs, 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 roots) that satisfy both of the following two equations.
5-1 WHAT IS A FILE EDITOR? Various types of files can be stored and recalled using the built-in File Editor function which has a total capacity of 1,917 steps. S FILE {Files are handled using filenames.) Any number of {ells, as long a5 the total number of steps does not exceed 1.917.
Press the [BE] key alter entering the filename. NEW FILE key in Password it needless press "EXE" "AC” for QUIT The display illustrated abase prompts entry of a password if required. If, in place of this display, the display clears and the cursor is blinking in the upper fell, see the section titled: PASSWORDS. The password function keep private data secure by making it impossible for anyone who doesn't know the password to access the data stored in the unit.
Pressing [ExE] moves the cursor one line down from its current position to indicate entry of the list data item, Operation Display EXE DE+2 As many data items as desired can be stored in a single file, limited only by memory capacity. The number of files created is also limited only by memory capacity.
Now enter the filename assigned to the desired file. Operation Display FleanpnenE~] FILE EDITOR 1 TRIANGLE >"TRIANGLE A prompt appears requesting the password when [86E] is pressed. The file is treated as a new file if the filename entered differs from that actually assigned to the file, and NEW FILE appears on the display. Should this happen, press and try entering the proper filename again. File contents are displayed immediately after filename input when the file has not been assigned a password.
5-2 COMMAND FUNCTION The command function is provided to make the file editor function easier to use. The commands used are different depending which file editor mode (file name input or.file data input) is being used. @ Filename input mode commands Press to enter the filename input mode.
M F command (Fred Bytes! Displays the number of e Ex. icing steps available for file input. Operation Display 0[] 11AAA 2:BBB 4:pDD >F 1023 Bytes Free W DEL command {Delete File) Deletes the file specified by “filename”, and is used to erase from memory any files no longer required. Ex.

W © (File name top) Though not actually a command, quotation marks are used in commands 1o enclose filenames. As noted previously, the quotation marks at the end of a filename may be omitted. M » (Positive integer} This command is not listed on the command menu, but it is convenient to use when recalling files. Files can be retailed by simply entering their menu number instead of the full name, Operation Display FILE EDITOR =—wmTIAARA 2:888 3:0C¢C e [an Person | .
MV command {Video Mode) Returns from the command mode to the file data input mode. Operation Display HONOOEE@ERMOZEE | SMITH Bl 0262~ } pressed by mistake [ SMITH B T command {Top) Moves the cursor from its present location to the beginning of the file. The first eight lines of the file are displayed after this command is executed. M B command (Bottom} Moves the cursor from its present location to the end of the file.
B S command {Search String) Locates and displays the first occurrence of a data item which includes the characters specified by the search element, with the cursor located under the first character, See the L command for locating multiple occurrences. The message “cannot find” is displayed if the specified search element does not exist. M L command {Long Search} Locates and displays all occurrences of data items which include the characters specified by the search element.
5-3 TAB FUNCTION A tab function can be used to easily line up columns of data in the file editor function. Tabs are entered using B (2 spaces), (Bl (3 spaces), and (4 spaces).
