CONSTITUTION:When the task executing control section 1 starts the task, a call number measuring section 13 obtains respectively a registration table 41, when the program is finished normally, the section 13 obtains a registration table 42 and when the program ends abnormally, the section 13 obtains a registration table 43 and the section 1 collates sequentially a task address (a) of a task to be executed and obtained by a task table index section 11 with a task address ai registered in the registration tables 41-43. When they are coincident, a corresponding parameter pi is extracted and the call number measuring program represented by a corresponding program address ci is executed by using the parameter pi. |
