摘要

PROBLEM TO BE SOLVED: To use a source code of the processing as it is regardless of the change of specifications of an inputted programming language. ;SOLUTION: A tag of an abstract syntax tree an the object of processing is checked to discriminate whether a node is a literal or a syntax (step S01). If it is a literal, the literal tag is checked to perform individually required processings (steps S02₁, S02₂,...). However, general processing (steps S02_j) for other literals is performed with respect to the literal requiring no individual processings. If it is a syntax, branching is performed in accordance with the tag, and individually required processings are performed for respective syntax classifications (steps S03₁, S03₂...). However, general processing (step S03_k) for other syntax is performed with respect to the syntax requiring no individual processings. In the case of a syntax, the processing is recursively performed from the step S01 with respect to all subtrees which the abstract syntax tree in the middle of processing has (step S04). The end of the tree structure can be discriminated if a node is a literal.;COPYRIGHT: (C)1999,JPO
