Description

[Detailed description of the invention]

<Technical Field> The present invention relates to a so-called pocket computer, which is a small-sized electronic computer having a statistical processing function, and particularly relates to the display of tabular data. <Prior art and its problems> Generally, in large computer systems that display tabular data groups,
We used a CRT display device, etc., which could display the entire tabular data, so we were able to easily confirm the item name of each data item in the tabular data group. However, small electronic computers that can be held and operated in one hand, so-called pocket computers, are equipped with only one or a few lines of display devices to keep them compact, and cannot display all tabular data groups. It's impossible. Therefore, in order to display a row or column, it is conceivable to first display the item name of that row or column, and then sequentially scroll and display each data in that row or column. , when sequentially scrolling the display, each data column was simply displayed, and even if you looked only at the displayed data, you could not tell which position and what kind of data the data represented. . Therefore, when performing tabular data, that is, statistical processing, on a small electronic computer, there has been a problem in that the statistical data cannot be easily checked. <Purpose> The present invention is a small computer equipped with the above-mentioned display device with a small display capacity, in which tabular data inputted for, for example, statistical processing can be easily checked on the display device. can be,
In particular, it is designed so that the operator can easily understand the position and content of the displayed data (numeric values) in the table data, thereby improving the operability of this type of small computer. This is an attempt to improve the results. <Summary of the Invention> For example, when the table below is stored in the memory in tabular form as tabular data, the display of tabular data in the small computer of the present invention is as follows:

[Table] If you display the position of the above table on a single line display device, it will display Aoki: Suigaku = 30, and if you display the position again, it will display Kato: Eigo = 63 and so on. This is done so that it is possible to know where in the data it is and what kind of content it is. <Embodiment> FIG. 1 shows the external appearance of a small electronic computer of the present invention, which is a so-called pocket computer that can be held and operated with one hand. A liquid crystal display device (hereinafter referred to as LCD) 2 is provided at the upper left of the small electronic computer (main body) 1, and a keyboard having character input keys and function keys is provided around it. Said LCD
2 is equipped with a dot segment type display capacity for one line of 24 digits, and furthermore, indicators 21, 22, 2 are provided at the bottom to display the mode status of the calculator.
3 and 24 are provided. Next, various keys, particularly keys related to the present invention, will be explained. Reference numeral 10 denotes a power switch, and by turning on this power switch, the power is turned on to the main body and the Yesialization process is performed. This initialization presets the mode of the main unit to statistical processing mode (STAT). Reference numeral 11 indicates mode setting keys; STAT key 11A sets the statistical processing mode (STAT) and calculation mode (CAL) alternately for each operation; and the STAT key 11A sets the program processing mode in BASIC language and the program execution (RUN) mode. and programming mode (PRO) alternately for each operation.
It consists of BASIC key 11B. In the STAT mode mentioned above, the indicator
STAT21 is lit and FAL2 is in CAL mode.
2 lights up, RUN23 lights up in RUN mode, and PRO24 lights up in PRO mode. 12 is a group of character input keys that can be defined as various function keys. Reference numeral 13 denotes a group of numeric input keys and a group of operation instruction keys, and a subtraction key 28 is defined as a missing value key that indicates the absence of item data in statistical processing by shift switching. The 14 key group is a function key group for calculating deviation values, average values, etc. in statistical processing based on display data. 15A, 15B, 15C, and 15D are cursor keys. 25 is a table key for creating and reading each table data for statistical processing, 26 is a line input key (↓ input) for selecting each item in the row direction when creating this display, and 27 is a This is a column input (→input) key that selects each item in the column direction. FIG. 2 is a circuit block diagram of a small electronic computer according to the present invention. 40 is a CPU, which executes data processing according to various control blocks stored in a ROM 45 connected to this CPU via a bus line. 41 is the aforementioned LCD, which is driven for display by a display control unit 42 connected to the CPU 40;
This display control section 40 has a built-in display buffer that stores display data (dot data). 44 is the keyboard device shown in FIG. 1, which supplies coded signals corresponding to the operated keys to the CPU 40. The ROM 45 includes an area 451 for storing an initial program that controls the initial setting process when the power is turned on, an interpreter area 452 for BASIC language, an area 453 for storing a statistical processing control program for the flowchart described later, and a CPU. Character pattern generator (CG) area 4 that develops a dot pattern for output (display in this example) from the code information of each generated character and symbol.
54, and an area 456 for storing various other system programs. Preferably, each of these areas is formed by a separate ROM chip. 46 is a RAM connected to the CPU via a pass line similar to the ROM 45, and includes an area 461 for storing a BASIC user program created arbitrarily by the operator, and a RAM created by the statistical processing of the present invention. Area 462 for storing multiple table data
and a system area 463 to which various buffers, counters, etc. are allocated. This system area 463 includes h, m, n counters and C, M,
N, A, B registers, etc. are formed. The table data area 462 is as shown in FIG.
Allocated to the BASIC variable data area. These data in FIG. 3 are stored for each input process described later or by a variable data assignment command of the BASIC program, and tabular data is created. The specific structure of the table data corresponding to Table 1 below is shown in FIG. 3, and each item of the table data has a fixed length of, for example, 16 bytes. In addition, in Fig. 3, 30 is the variable name of each column item title, which is allocated and stored together with the number of items (actually the number of column items + 1), and title data 31, 31, etc. are subsequently stored. There is. 32 is the table title of the table data (Table 1) allocated following the title data. Numeral 33 is a variable name for each line item title, which is allocated and stored together with the number of line items, and title data 34, 34, . . . of the line items are subsequently stored. Numeral 35 is a data variable name, which is allocated and stored together with the number of items M and N, and data 36, 36, . . . for each item are stored below. These item data are automatically allocated in memory each time input processing is performed, and also by variable commands in the BASIC language. Further, for access to read each item data, the address value of the item data position is calculated based on the number of items stored together with the variable name. The above allocation method can be used, for example, in JP-A-57-43246.
It is known for. In the figure, 38 is data indicating non-input, which is represented by the minimum value with a negative sign added, and when the variable name 35 is assigned, this non-input data is stored in all the corresponding item data areas. Further, numeral 39 in the figure is data indicating the absence of data, which is represented by the maximum value with a plus sign, and is stored when the missing value key 34 is operated. Using the numerical data of the minimum/maximum values for these data may be possible by using special codes as these identification data, but this device
This is to avoid placing any restrictions on the code system, as it enables program processing in BASIC languages and uses various code systems. Another problem is that in data processing, the maximum/minimum value of the data processing capacity of the device almost never occurs.

[Table] ↑
Line item Next, the operation of the above configuration will be explained. First, the table data shown in Table 1 above is stored in the table data area 462 as shown in FIG. This is done by operating the table key 31 in FIG. 1 and then inputting a table title using the character keys 12, and this table title data is stored in the table data area. Further, by operating the character key 12 that is input after operating the column item input instruction key (input → ) 33, the column item data 31, 31, ... are stored sequentially, and then the row item input instruction key (↓ Input )32
The line item data 34, 34, . . . are stored by operating the character key 12 following the operation. By repeating these steps, the row and column title data are stored, and when the row item input instruction key (↓input) 32 is operated again, the title of the next row item is input. Since the line is unnecessary, operating the instruction key 32 again will instruct you to input numerical data, and by operating the cursor key 15, the desired numerical item area 36,
36,... and each data based on Table 2,
Input from numeric keys 13. Incidentally, at this time, the aforementioned uninput data is stored in all the numerical value item areas, and this data will be rewritten. Therefore, unless a numerical value is input, uninput data remains stored. Hereinafter, statistical processing will be explained assuming that tabular data is created according to the example of Table 1 and stored as shown in FIG. In FIG. 4A, when the table key 25 is operated to check each item data after creating the table data described above, steps S11 and subsequent steps are executed. The h counter that means the variable name in the table and the m and n counters that indicate the position of each item area are reset, and based on this h counter, the variable name area 30 of Th$, that is, Tφ$ is loaded, and the number of items (number of column items) is reset. Load (C) into the C register. (S11, S13) Furthermore, based on the number of items, the item data of Th$(C-1), that is, Tφ(4)32, is imported, and the character data of “Hyouyo Title Fake Sekihiyou” is imported.
The image is developed into a dot pattern by the CG 454, transferred to the display buffer 43, and displayed. (S14,S
15) Next, Dh$ or Dφ$ variable name area 3
3 is taken in, the number of line items (L) is transferred to the L register, and Dh, that is, the Dφ variable name area 35 is taken in, and the number of items (M, N) is transferred to the M, N registers. (S16 to S19) After that, when selecting another table data, operate the table key 25 to increment the h counter by 1. or,
When other keys such as cursor keys 15A to 15d are operated, the process shifts to DS30 in FIG. What to keep in mind here is h (φ in this example), which identifies the table data in the selected table data,
The number of column items is stored in the C register, the number of row items is stored in the L register, and the number of data items is stored in the M and N registers. In FIG. 4D, when the cursor right movement key 15A is operated, S3
1 and subsequent steps are executed, and cursor left movement key 15
When B is operated, S35 and subsequent steps are executed, and when the cursor up key 15C is operated, S50 is executed.
When the cursor down key 15d is operated, S56 and subsequent steps are executed. In a state where the short title is displayed, m=φ and n=φ. In this state, when the cursor 15A key is operated, the m counter is incremented by 1, and the variable indicated by Thφ(m-1), that is, the column item data 31, is read out.
Item data is supplied to the display device and displayed. The above operation is performed while the cursor is at n=φ.
It is repeated every time the A key is pressed, and the column item area 31
are sequentially captured and displayed in the right direction in the figure (top right direction in Table 1). (S31, S32, S33, S40,
S41) By repeating this cursor 15A key, m
=C-1, that is, when the rightmost end of the column item is being displayed, the m counter is reset (m=φ, n=φ) and Tm$(C-1), that is, the item area 32 is taken out. Then, “Title=Item Data (Synonyms)” is displayed again. (S31, S32, S34, S42, S4
3) If you operate the cursor left movement key 15B again, S
35 and subsequent steps are executed, and m-1→m is executed in reverse to the above, and the column item areas 31 and 31 are sequentially read and displayed in the left direction in the figure (to the left of the top row of Table 1) for each operation. . (S35, S36, S37, S
38, S40, S41) If you operate this key in the state of m=1, Th
$(C-1), that is, the item data of the table item area 32, is imported, and "Hiyo title = Item data (Seiseki Hiyo)" is displayed. Also, when this key is operated in the state of m = φ, the column item The rightmost column item name is displayed. (S35, S36, S37, S40, S41,
Or S35, S36, S39, S40, S4
1, or S35, S36, S37, S38, S
42, S43) On the other hand, when the cursor up key 15C is operated, steps S50 and subsequent steps are executed, and with m=φ, the n counter is incremented by 1, and Dh$(n-1), that is, the line item data 34, 34, . . . But cursor key 15
For each operation, "item data (Aoki, Kato,...)" is displayed in sequence. This is sequentially captured and displayed to the right from the position marked 34 in FIG. 3 (downward at the leftmost end of Table 1).
(S50, S51, S52, S53, S54) If the displayed line item area is the last line item (the lowest line item in Table 1), the n counter is reset and the above-mentioned S42 and S43 are executed.
(S50 to S54, S55) When the cursor down key 15d is operated, the line item data is sequentially displayed in the opposite direction. (S56
~S60) As mentioned above, when n=φ, press cursor key 1
When 5A or 15B is operated, the column item names are rotated to the right or left of Table 1 and displayed. Also, when m=φ, press cursor key 15C or 15
When d is operated, the row item names are cycled downward or upward in Table 1 and displayed. Furthermore, m=φ, n=φ
In this state, the table title name is displayed. In the above operation, if the cursor 15A, 15B keys are operated in the state where n≠φ, then m≠φ
If the cursors 15C and 15D are operated in this state, the display shifts to the data item area. This effect is shown in FIG. 4C. That is, when the cursor 15A key is operated in a state where n≠φ, the process shifts to FIG. 5C. In S70, it is determined whether the cormorant is displaying m=H, that is, the rightmost item in the data item area, and if it has not been reached, m+1→m is executed, and Th
$(m-1) item data, i.e. column item 3
The area with the corresponding item name among 1, 31, . . . is selected, and the data is transferred to the B register. For example, if m=1, the Tφ$ (middle) column item area 31 in FIG. 3 is taken in. (S70, S74, S7
5) Next, the item data of Dh$(n-1) is A.
stored in a register. For example, if n=1, the Dφ$(φ) line item area "Aoki" in FIG. 3 is captured. (S26) It is compared whether the sum of the number of characters in the A register and the number of characters in the B register is less than or equal to a predetermined value l, for example 13 characters, and if the value is larger than l, the A register and the B register are are compared, and the last character of the item data string to be stored in the larger register is removed. This process is repeated, and if A+B≦l, numeric data is imported from the data item area 36 based on the m and n values, and the row item name of the A register and the column item name of the B register with the above-mentioned number of characters adjusted. At the same time, the above numerical data is displayed. Furthermore, if m=1 and n=1, "Aoki: Suugaku=30" is displayed. (S76 to S82) The processing in S77 to S80 described above is performed in advance because the display capacity of the LCD is limited and displaying all characters of row items and column items stored in table data will limit the number of display digits of numerical data. Row item names and column item names are displayed with part of the item name omitted within a predetermined l value. As shown in the flowchart below, the corresponding row item name and column item are displayed simultaneously for each cursor operation. Each time you operate cursors 15A and 15B, n
When the rows determined by the values are sequentially displayed by cycling to the right or left of Table 2, and when the cursor 15A is operated from the rightmost item in Table 1, or when the cursor 15B is operated from the leftmost item in Table 1, , only the line item names displayed in Figure 4B will be displayed. (S73) Each time the cursors 15c and 15d are operated,
When the columns determined by the values are sequentially cycled downward or upward in Table 1 and the cursor 15c is operated from the bottom row of Table 1, or when the cursor 15d is operated from the top row of the data items of Table 1. If you operate , only the column item names shown in Figure 4B will be displayed. (S90) As described above, when displaying numerical data in table data for confirmation, it is necessary to use a device with a small number of display lines in order to simultaneously display the row item name and column item name corresponding to the data. You can also perform confirmation processing. Here, the display form of the display device described above is
To summarize with reference to the table, when the position of in Table 1 (on the table data area) is specified, Aoki: Suugaku = 30 is displayed, and when the position of in Table 1 is specified, Aoki: Eigo = 80 is displayed, and when the position of 〓 in Table 1 is specified, Yokota: Kokugo = 39 is displayed, and the row item name, column item name, and corresponding numerical data are displayed in order. You can easily see what kind of data is at what position in the table data. Also, when the position of Table 1 is specified, it is displayed as ``Saito〓ken:suugaku=37'', and this is because the number of characters in the row item name and column item name exceeds the predetermined number l. The part is omitted and the number is expressed within l. <Effects> As described above, the present invention includes a tabular data memory that is divided into multiple rows and columns and stores each item name and character or numerical data in each row/column. In a small electronic computer in which the contents of the table data memory are displayed on a display means having fewer rows than the number of rows, for example, one display row, the data in the designated row/column of the display data memory on the display means By displaying the item name of the row and column corresponding to the indicated position as a display, as well as character or numerical data at the indicated position, the operator can understand the contents of the displayed data at which position. This makes it easy to understand what is going on, and it is extremely convenient for statistical processing that deals with tabular data.
