Abstract

PURPOSE:To reduce the load of a host language compiler and to shorten the translating time by providing a setting means which sets a reference flag to a symbol table and a means which turns the unreferred data into a nameless item with use of the reference flag of the symbol table in a precompiler. CONSTITUTION:A generating part 4 which outputs a host language source program 1a2 calls out a part 6 which turns the unreferred data into a nameless item when generating a date part from a symbol table 7. Then the part 6 decides ON or OFF of a reference flag. If the ON state is confirmed, a name is outputted as it is out of the table 7. Meanwhile a nameless item of host language is outputted when the OFF state is confirmed. Thus the user defining label that is not referred to in a source program 8 is outputted to the program 12 as a nameless item.

It is equipped with means for converting.

７を作成する。First, the precompiler inputs the source program 8 and decomposes it into lexical units using the lexical analysis unit 1 and outputs it to the work file 9. The syntactic analysis unit 2 inputs a work file 9, performs syntactic analysis, outputs information necessary for semantic analysis to a work file 10 as text, and creates a symbol light 7 from a user-defined name.

ＩＬＬＥＲ。Next, in the present invention, when the uniqueness is confirmed, the semantic analysis s3 calls the reference flag setting unit 5 and turns on the flag indicating that the entry in question in the symbol table T has been referenced. . This flag is prepared for each user-defined name (one entry of the symbol light T), and is
When the symbol light 7 is created, it is OF'F. This semantic analysis unit 3 outputs information necessary for generation to a work file 11 as text. The generation unit 4 then inputs the work file 11 and outputs the host language source program 12. Here, when generating from the symbol light 7 of the data section, the generation section 4 calls the hairless itemization section 6 of unreferenced data. Then, the hairless itemization unit 6 of this unreferenced data determines whether the above-mentioned reference flag is ON or OFF'F,
If ON, the name of symbol light 7 is output as is, and OFF
