AUTOMATIC GENERATION METHOD FOR PROGRAM

PROBLEM TO BE SOLVED: To automatically generate programs of a large number of specifications by embedding plural special comments in the generated program by describing a mark in the optional specification part of program specifications and permitting free coding between the comments. SOLUTION: When an already generated program 100 is present, a part coded by a user is extracted from the program 100 and stored in a user coding table 102. Then, a program fragment 105 is generated from the program specifications 103. In the generated program fragment 105, the comments for indicating the start and the end of coding by the user are inserted. A program synthesis part 107 reads a program skeleton 106 and outputs the program 100. In this manner, the user can add coding to arbitrary part of the generated program 100. Thus, the range of generatable program specifications is enlarged.
