FORTRAN77程序中非结构分支语句的结构化

Structuring of Unstructured Branches in FORTRAN 77 Programs

首先将非结构成分加以分类，对两个分支转向语句的交错重叠的四种情况建立了识别分析模型，并给出非结构化模式的识别和判别算法．然后利用分离、复制等方法，对四种非结构化模式加以结构化。

Unstructured components are classified and the identificatoin models for four interleaved but overlapping cases of two branch GOTO statements are developed. The algorithm for identifying and discriminating the unstructured model is given. By the splitting and copying techniques, four unstructured modes are structured.
