Abstract

A GDMO translator is provided, which is capable of generating output files with various syntaxes from an input file with the same syntax, and which is capable of describing different outputs containing, for example, an indefinite number of nesting structures. A parser 140 reads an input file and produces an abstract syntax tree by conducting an analysis according to a prescribed syntax. The abstract syntax tree is then stored in the abstract syntax tree data base 120 through the data base access means 130. The translation means 80 reads the output template 100 through the syntax reading means 60 and the lexical analysis means 70. The translation means 80 generates the output file, while on one hand, accessing the syntax tree data base which stores the syntax tree representing the input file content, following the output template file 100, and, on the other hand, realizing the nesting structure with indefinite depth using a file stack for recording the position of the recursive control, or conducting a conditional branch processing.
