The indicated cursor judgment position (SX, SY) is RAM
8 will be stored.

Next, when changing the display direction of the character display area 25 in this state, the first display position setting routine shown in FIG. 4 is executed. When this first display position setting routine is executed, it is first determined whether or not switching of the display direction of the character display area 25 has been instructed. The process is repeated until the end (S1).

If it is determined in step S1 that the display direction of the character display area 25 has been instructed to change, the answer is YES.
S2 is executed as follows, and it is determined whether the switching instruction is to switch from vertical display to horizontal display (S2). If it is determined that the switching is from vertical display to horizontal display, S4 is executed as YES, and whether or not the cursor position CY in the Y direction is larger than the cursor determination position SY in the Y direction is determined. (S4).

By executing S4 above, the cursor position C
If it is determined that Y is smaller than the cursor determination position SY, the cursor is located within the character display area 25 after being switched horizontally, so S10 is executed as NO, and the character display is After the display direction of area 25 is switched (S10), the display start position (DX, DY)
The data from is output to the character display area 25, and
The cursor will be output at the cursor position (CX, CY) (S11).

On the other hand, if the execution of S4 above determines that the cursor position CY is larger than the cursor determination position SY, the cursor is not located within the character display area 25 after being switched horizontally. , YES as S
5 will be executed, and the display start position DY in the Y direction will be executed.
' will be calculated using the following formula.

DY'=DY+(CY-SY) Note that DY, CY, and SY above refer to the display start position in the Y direction, the cursor position, and the cursor determination position (S
5).

Once the display start position DY' is calculated, the cursor determination position SY is then set as the new cursor position CY' (S6). After the display direction of the character display area 25 is switched (S10), data from the newly set display start position (DX, DY') is output to the character display area 25, and the cursor is moved to the cursor position. (CX, CY') (S11).

Furthermore, if it is determined in S2 that the switching is not from vertical display to horizontal display, a NO is returned and S7 is executed, and the cursor position CX in the X direction is lower than the cursor determination position SX in the X direction. It is determined whether or not the value is also larger (S7).

By executing S7 above, the cursor position C
If it is determined that After the display direction of area 25 is switched (S10), the display start position (DX, DY)
The data from is output to the character display area 25, and
The cursor will be output at the cursor position (CX, CY) (S11).

On the other hand, if the execution of S7 above determines that the cursor position CX is larger than the cursor determination position SX, the cursor is not located within the character display area 25 after being switched horizontally. , YES as S
8 will be executed, and the display start position DX in the X direction will be executed.
' will be calculated using the following formula.

DX'=DX+(CX-SX) Note that DX, CX, and SX above refer to the display start position, cursor position, and cursor determination position in the X direction (S
8).

Once the display start position DX' is calculated, the cursor determination position SX is then set as the new cursor position CX' (S9). After the display direction of the character display area 25 is switched (S10), data from the newly set display start position (DX', DY) is output to the character display area 25, and the cursor is moved to the cursor position. (CX', CY) (S11).

The size of area 25 is assumed to be 6×4. Then, as shown in Figure 6, set the display start position (DX, DY) to (0, 0) and the cursor position (CX, CY) to the position where "ni" of (1, 4) is output. , cursor judgment position (SX, SY
) is (3, 3), the character display area 25 will be displayed in the state shown in FIG.

When the character display area 25 is switched from vertical display to horizontal display under the above setting conditions, the cursor position CY=4 in the Y direction and the cursor determination position SY=3 are compared. Since the cursor position CY=4 is a larger value than the cursor judgment position SY=3, a new display start position DY'=1 is calculated from the above calculation formula, and the cursor judgment position SY= 3, a new cursor position CX'=3 is obtained.

[0044] As a result, the display start position (DX, DY'
) is (0,1), cursor position (CX,CY') is (1
, 3), and when the character display area 25 is switched to horizontal display, as shown in FIGS.

If it is determined that the added value is larger than the document data end position MX, the right end of the character display area 25 after switching exceeds the right end of the document data storage area 31, so YES is determined and S46 is executed. become. As a result, the display end position DX2 is replaced with the document data end position MX, and the display start position DX1 is changed to (
Display end position DX2 - horizontal size CNTX + 1), and the right end of the character display area 25 is matched with the right end of the document data storage area 31 (S4
6).

On the other hand, if it is determined in S45 that the added value is smaller than the document data end position MX, the right end of the character display area 25 after switching is located within the document data storage area 31, and NO is returned. S47 will be executed. Then, the display start position D calculated in step 54 above
By determining whether X1 is smaller than 0, it is determined whether the left end of the character display area 25 after switching exceeds the left end of the document data storage area 31 (S
47).

If the display start position DX1 is determined to be smaller than 0 as a result of the determination in S47 above, the character display area 25 after switching will be out of the left end of the document data storage area 31, so S48 is returned as YES. It will be executed. As a result, the display start position DX1 is set to 0, and the display end position DX2 is set to (horizontal size CNT
X-1) will be set, and the left end of the character display area 25 after switching will match the left end of the document data storage area 31 (S48).

On the other hand, if it is determined in S47 that the display start position DX1 is larger than 0, the character display area 25 after switching is located within the document data storage area 31, and the display start position DX1 and display S49 will be executed as NO without changing the end position DX2.

[0084] This S49 is similar to S46 and S48 described above.
It is also executed after the execution of , and the vertical direction start position processing routine, which has been made into a subroutine, is called (S49). This vertical direction start position processing routine executes the following calculation formula, as shown in FIG.

DY1=CY-[(CY-DY1)/(DY2-DY1
+1)]×CNTY Nao, DY1, CY, DY1, DY2
, CNTY is the display start position in the Y direction, the cursor position,
These are the display start position, display end position, and horizontal size.

The display start position DY1 calculated by the above formula is, for example, as shown in FIGS. 16 and 17.
A cursor output at a position of e:f ratio from the upper and lower ends of the horizontally displayed character display area 25 and the vertically displayed character display area 2
After switching the display direction, the cursor output at the position of the ratio g:h from the upper and lower ends of
: h). After the new display start position DY1 is set using the above calculation formula,
The process returns to the third display position setting routine of step 2 (S55).

Upon return from the vertical start position processing routine described above, S50 is executed, and in S50 to S53, the positional relationship between the character display area 25 and the document data storage area 31 in the Y direction is confirmed. , the character display area 25 is corrected to be located within the upper and lower ends of the document data storage area 31.

That is, it is determined whether the sum of the display start position DY1 in the Y direction and the vertical size CNTY of the display size storage area is larger than the document data end position MY, and the lower end of the character display area 25 after switching is determined. It is determined whether S exceeds the lower end of the document data storage area 31 (S
50). If it is determined that the added value is larger than the document data end position MY, the lower end of the character display area 25 after switching exceeds the lower end of the document data storage area 31, so YES is determined and S51 is executed. become. As a result, the display end position DY2 is replaced with the document data end position MY, and the display start position DY1 is changed to (
display end position DY2 - vertical size CNTY + 1), and the lower end of the character display area 25 is matched with the lower end of the document data storage area 31 (S5
1).

On the other hand, if it is determined in S50 that the added value is smaller than the document data end position MY, the lower end of the character display area 25 after switching is located within the document data storage area 31, and NO is returned. S52 is executed, and S55
It is determined whether the display start position DY1 in the Y direction calculated in is larger than 0 or not. As a result, it is determined whether the upper end of the character display area 25 after switching is located within the document data storage area 31, and if it is determined that the display start position DY1 is larger than 0, Since the upper end of the character display area 25 after switching is located within the document data storage area 31, the process ends without changing the display start position DY1 and the display end position DY2 (S52).

On the other hand, if it is determined in S52 that the display start position DY1 is greater than 0,
Since the upper end of the character display area 25 after switching is out of the document data storage area 31, S53 is executed as YES. As a result, the display end position DY2 is set to 0.
is set, and (vertical size CNTY-1) is set in the display start position DY1, so that the upper end of the character display area 25 after switching will match the upper end of the document data storage area 31. (S53).

[0091] In this way, the information processing apparatus of this embodiment has the following features:
By rotating the display unit 3, it is possible to change the setting of horizontal or vertical display of the character display area 25, so it is possible to create a document in the optimal display direction for the document format, increasing efficiency during editing. It is now possible.

Furthermore, the information processing apparatus of this embodiment has a third
By executing the display position setting routine every time the display direction of the character display area 25 is switched, it is possible to always position the cursor within the character display area 25 in the state before switching, and the document data storage area Since the character display area 25 can be positioned within the cursor 31 and the relative positions of the cursor before and after switching can be approximated, it is possible to further improve the efficiency when creating a document.
