Abstract
A method and apparatus for analyzing a DO-statement to determine the type of a DO-variable and for determining whether a sign of an incrementation parameter at the time of compile can be determined are provided in a DO-loop object code generator in a compiler to select an object code generating method corresponding to the state of the DO-loop. As a result, object codes fitted to each DO-loop are generated which are so efficient as to improve the iteration count according to the ANSI standard, saving of use of registers, elimination of unnecessary calculation and the like.
