PURPOSE:To save the time and the labor required for production of a user program by instructing the read of the definition information corresponding to plural screens of a process in accordance with the display order of screens when the process is started. CONSTITUTION:A screen transition control means 151 controls the transition states of the screens corresponding to the processes requiring the display of plural screens, i.e., the display order of screens. Then the means 151 gives the read instruction of each definition information in accordance with the display order when a user program is carried out and the start of a process is instructed from an instruction means 111. A screen display control means 141 reads the corresponding definition information out of a store means 121 with the read instruction. Thus the means 151 controls the transition state of the display screen, and the user program is just required to instruct the start of a process requiring the display of plural screens. Thus it is possible to reduce the production load of the user program. |
