A keyboard and a mouse (pointing input device) for inputting commands and instructions, a printing device for outputting a hard copy of data as required, an external storage device for holding data, and the like. In such an interactive data system, when a necessary instruction is given by a keyboard or a mouse, a response to this instruction is immediately reflected on the display of the display device screen, and new instructions are repeatedly and repeatedly given to this response. As a result, the processing result that the user seeks is obtained.

Some of such interactive computer systems have a function of displaying graphics on a display screen, and can display various graphics at desired positions in desired sizes. Also,
A plurality of figures are displayed on the display screen, and when these figures are edited, each figure is treated as one group,
In some cases, when an instruction for this group is input, each figure belonging to the group is processed collectively.

For example, when moving or enlarging or reducing a plurality of graphics displayed on the display screen, these graphics are treated as one group, and when the movement or enlargement / reduction is instructed for this group, each of the graphics becomes It is moved or enlarged at once.

If the processing is performed in a group as described above, it is not necessary to perform the processing for each of a plurality of figures, so that the operation for the processing can be simplified, and the operation omission and operation error can be prevented. Can be.

However, such a batch processing system performed in units of groups is prepared in advance, and if a plurality of types of batch processing are prepared, any one of these processes can be selected. If the desired process is not included in each of the processes, the respective processes must be repeated for each of the plurality of figures.

For example, a plurality of graphics R as shown in FIG.
1, R2, R3, and R4 are displayed. When these figures are treated as one group and enlarged in the width direction and reduced by the height method, each figure R'1, R as shown in FIG. ′ 2,
R'3, R'4 can be obtained. At this time, if it is desired that the width of each figure R'2, R'4 is not changed and the width of each figure R2, R4 is the same, The batch processing is not appropriate. In this case, after performing the above collective processing, in the width direction of each of the figures R'2, R'4, the width of each of the figures R'2, R'4 is equal to the width of each of the figures R2, R4. Perform each reduction process, or from the beginning each figure R1, R2, R3, R
It becomes necessary to perform reduction processing in the height direction and enlargement processing in the width direction for each of the four steps, and it is not possible to make full use of batch processing in group units.
