Abstract

Halstead in his Theory of Software Science, proposed that in the Fortran language, each occurrence of a GOTO i for different label i's be counted as a unique operator. Several writers have questioned the wisdom of this method of counting GOTO's. In this paper, we investigate the effect of counting GOTO's as several occurrences of a single unique operator on various software science metrics. Some 412 modules from the International Mathematical and Statistical Libraries (IMSL) are used as the data base for this study.
