PURPOSE:To decrease the number of calculations and the time of pointer tracings and to simplify data size calculation, by retracing texts from the last intermediate text and adding the data size to an intermediate text that a parent pointer indicates. CONSTITUTION:The data size 4 of an intermediate text (tex)G is added to the numeral 0 in its parent data storage area 4. Then, a TexF is retraced by the backward pointer (BP) of the TexG to add the number of data of the TexF, i.e. 3 to its parent TexC similarly. A TexE is retraced by the BP of the TexF to its number of data, i.e. 2 to its parent TexC. Similarly, the number of data of a TexD, i.e. 1 is added to its parent TexC. Consequently, the integrated number of data of the TexC is 10. Further, the value is added to the parent TexB of the TexC and the sum is added to a TexA, completing the calculation. |
