Abstract: Some key problems appearing in the process of ATLAS translator design such as too great a number of ATLAS keywords, the extending problems of ATLAS in a new field, translation and interpretation of ATLAS signal related statements, and the correspondence between virtual resources and factual resources are studied. Symbol table technology is introduced to solve the capacity limitation problem of lexical analyzing tool (LEX); Both file technology and symbol table technology are used to implement the extended ATLAS problems; Database technology and Component Object Model(COM) technology are put forward to resolve the problems of signal statement translation and resources locating & calling problems in the process of signal statement translation in ATLAS. The above-mentioned methods have been applied in the project of ATLAS translator construction suceeded in the translation of related test programs in analog test field. And the ATLAS translator works well.

Key words: general test language ATLAS (Abbreviated Test Language for All System), compiler design, symbol table, COM(Component Object Model) technology
