In the character processing apparatus having the above-mentioned configuration, when the determination area 1a calculates the editing area from each variable input for a plurality of format setting items and denies the possibility of format setting, the instruction means 1a 1b displays a format setting item that can be corrected based on the determination result of the determination unit 1a.
T7), a search instruction is given, and the calculating means 1c calculates the settable range of each variable that can be corrected for the specified format setting item and displays it on the display means (CRT7), and displays the corrected item and the set range of the variable. Identify easily.

In this embodiment, the CPU 1 controls each means 1a.
1c, but each of the means 1a to 1c may be constituted by independent means.

FIG. 2 is a schematic diagram showing an example of a format setting screen displayed on the display 7 shown in FIG. In this figure, the set value of each item for which a numeric value can be entered for an item displayed as “■” is set and displayed in “[]” in the figure. “■” in the figure can be moved up and down on an unselected item “□”. Therefore, “■” can be moved on each of the items 11 to 19.

The item 11 corresponds to a paper size setting item, and the size of the paper to be printed can be input. Item 12 corresponds to a character number setting item on one line, and the number of characters that can be input on one line can be input.
Item 13 corresponds to the line number setting item for one page, and the number of lines that can be input for one page can be input. Item 14 corresponds to an inter-character pitch setting item, and the width between characters can be designated and input. Item 15 corresponds to the line pitch setting item, and allows the user to specify and input the width between characters and the length between characters. Item 16 corresponds to the upper margin setting item, and the length from the upper end of the sheet to the upper end of the character on the first line can be designated and input. Item 17 corresponds to the lower margin setting item, and the length from the lower end of the sheet to the lower end of the character on the last line can be designated and input. Item 18 corresponds to the left margin setting item, and the length to the left end of the first digit character can be designated and input. Item 19 corresponds to the right margin setting item, and the length from the right end of the sheet to the right end of the last digit character can be designated and input.

Therefore, the width of the paper satisfies the following condition: paper width ≦ (right margin) + (left margin) + (number of characters in one line) × (width of one character) + (character pitch) × (1 Number of characters on a line -1) The length of the paper must satisfy the following conditions.

Paper length ≦ (top margin) + (bottom margin) +
(Number of lines per page) x (length of one character) + (line pitch) x
FIG. 3 is a schematic diagram showing an example of a format re-setting screen displayed on the display 7 shown in FIG. 1, and a display example when the above condition is not satisfied. Corresponding to

In this figure, "□" indicates an item that may be corrected if corrected. However, just changing one item does not necessarily mean that the normal state is immediately established. “■” indicates the item being input, and only the item whose display state is “□” can be moved, and only the item that can be modified can be modified. When "@" is moved by the key operation and the input item is changed, the inputtable range of the input item in that state is displayed. If the normal state cannot be achieved by correcting only the input items, the inputtable range is not displayed.

The items 11, 12, 14, 18, 1
In a state where only 9 is searched for on the CRT 7, the user corrects and inputs these items 11, 12, 14, 18, and 19 while looking at the calculated settable range information 20. Determine the format of

Hereinafter, the format setting operation in the character processing apparatus according to the present invention will be described with reference to the flowchart shown in FIG.

FIG. 4 is a flowchart showing an example of a format setting procedure in the character processing apparatus according to the present invention.
Note that (1) to (10) indicate each step.

When the key input processing is performed (1), the input key code is discriminated (2), and when something other than a numeral or cursor movement is input, step (3) is performed. To execute various processes (other processes) corresponding to the input key code.

On the other hand, if a numeric key is input in the key determination process of step (2), each variable is set in a random access memory (RAM) 3 in order to calculate the input numerical value (4). ). Next, based on each variable, FIG.
Perform each format calculation for the paper width and paper length shown in the example of (5). According to this calculation result, the above conditions,
Judge whether it is an error condition that cannot satisfy
(6) If YES, set the error flag; if NO, clear the error flag.

On the other hand, if the cursor movement key is depressed in the key judgment processing in step (2), a next position search processing for searching for a movable item is performed (7). This means that the item in which “□” is first detected in the moving direction is the movable item. Since the detection method can be realized by a known technique, the details are omitted.

Next, it is determined whether or not an error is occurring from the setting state of the error flag (8).
Go to 0) and if YES, calculate by solving the equation by substituting the settable range into the above condition (9)
. For example, if “■” is present in the right margin of item 19 and an error has occurred, the following equation is set with the right margin = x.
Calculate the settable range by solving (1).

Paper width = x + (left margin) + (one line sentence +
(Number of characters in one line) x (width of one character) + (pitch between characters)
× (number of characters in one line -1) (1) Solving the above equation (1), if there is no positive solution, there is no settable range. If the settable range exists, the set range can be displayed by obtaining the maximum value of x.

Next, the input numerical value, the cursors "□" and "@", the message at the time of occurrence of the error, and the settable range are displayed at predetermined positions on the display 7 as shown in FIG. It is displayed as a numerical value or the like (10), returns to step (1), and repeats the above step processing.

In the above-described embodiment, a case has been described in which all possible items are listed as modifiable items. However, an item that can avoid a formatting error only when the variable is actually changed is described. Only the correction items may be listed.

[0025]

As described above, according to the present invention, there is provided a judging means for calculating an editing area from each variable input for a plurality of format setting items to judge the possibility of format setting, and a judgment by the judging means. Instructing means for instructing the display means to search for a modifiable format setting item based on the result, and calculating a settable range of each modifiable variable for the format setting item designated by the instructing means, and displaying the settable range on the display means. With the calculation means, if the format set by the user is inappropriate, the user can clearly specify and indicate the format setting item to be corrected, and set each variable of the format setting item to be corrected. The range can be easily specified.

Therefore, the user can reduce the burden of correcting the format, and can complete the format correction which can be determined in a short time without error.
