Use of an environment classification model

Various reference models have been proposed for the classification of features present in an integrated software engineering environment. Two such models are studied and a target system is mapped to the set of services present in these models. This system consisted of approximately 23000 lines of Pascal source code in 31 modules and provided tools for developing Pascal programs using either a syntax-directed editor or a line-oriented editor. In addition to describing the system, this mapping exercise provided additional feedback on the effectiveness of the two reference models used. The results of this mapping and comments on the effectiveness of the models are given
