摘要：PURPOSE:To shorten the executing time of a compiler by deciding and

detecting a replaceable operator to an arithmetical formula including a mixed operationof the complex number type data and another type data and changing the operationorder of the arithmetical formula. CONSTITUTION:A mixed operation detecting means 3analyzes a source program 1 and decides whether an arithmetical formula includes or nota mixed operation of a complex number type data and another type data. An operationorder change detecting means 4 decides whether an operation of a type other than thecomplex number type that can be calculated is included or not before a complex numbertype operation against said detected mixed operation. An operation order changeprocessing means 5 changes an internal table of a compiler so that the detectedoperation of a type other than the complex number type one is carried out before thecomplex number type operation. Then a code generating means 6 produces an objectprogram based on the changed internal table of the compiler.
