PURPOSE:To reduce the load of a user program and to effectively set and take out the information by preparing a function to set the information to a coding/ decoding table and a function to take the information out of the table and therefore setting and taking out the information with no consciousness of the type of a structure and the information. CONSTITUTION:An information setting function 8 and an information take-out function 9 are prepared to set the information onto a coding/decoding table 4 and to take the information out of the table 4 respectively. When both functions 8 and 9 are called, the return value including the frame of a structure and the type of a variable is obtained. These functions 8 and 9 are produced by a structure producing device 2 based on an abstract syntax 1. Then a user program 7 sets the information to the argument of the function 8. Thus the information obtained from the function 8 in consideration of the frame of the structure and the type of a variable is set on the table 4. Thus it is possible to set or take out the information with no consciousness of the frame and the type of the structure. As a result, the load of the program 7 is reduced and the information setting/taking-out efficiency is improved. |
