PURPOSE:To reduce load of garbage collection by providing an area used exclusively for fixed data on a memory map, declaring fixation of data structure by specified function, and shifting the structure from a dynamic memory area to an area for fixed data. CONSTITUTION:To shift a specific list structure to a fixed list area, a function such as (FIXQ variable name) is prepared. When FIXQ is inputted, an objective list (variable) is copied from an area in use to a temporary fixing area, and registration of objective list is erased from utilized area. Then, the size TFS of the temporary fixed area is updated adding the size of the objective list, and an area for fixed list 18 is secured in a heap area. When reedition of once fixed list structure is desired, (UNFIXQ variable) is prepared, and thereby the list structure is copied from the fixed list area to the heap area, and alteration is made possible. In this case, those which were in the fixed list area become garbage, garbage collection of the fixed list area is made. |
