PURPOSE:To easily specify an optional position on a bit map screen in a program for executing graphic processing by previously specifying a position on the bit map screen, storing the position by XY coordinates correspondingly to a position ID and extracting the stored position by the program. CONSTITUTION:A position ID setting program 3 reads out the XY coordinates of a specified position on the bit map screen displayed on a display part 2 by a mouse 4-1 or the like. The XY coordinates are previously stored in bit map screen data structure 1 correspondingly to a position ID, and at the time of executing the program 6, a program execution control part 7 extracts the XY coordinates corresponding to the position ID specified by the program 6 from the structure 1 to execute display or the like based upon the position. Consequently, a required position on the bit map screen can be easily specified by the program 6. |
