Abstract
FGSPEC is a wide spectrum specification language intended to facilitate the software specification and the expression of transformation process from the functional specification which describes “what to do” to the corresponding design (operational) specification which describes “how to do”. The design emphasizes the coherence of multi-level specification mechanisms and a tree structure model is provided which unifies the wide spectrum specification styles from “what” to “how”.
