Techniques for the formal definition of the G-LOTOS syntax

Some approaches for formally defining the graphical syntax of LOTOS, called G-LOTOS, are discussed. An extended grammar approach is contrasted with one based on an abstract syntax for LOTOS; the usefulness of definite clause grammars is also considered. The advantages and disadvantages of the different approaches are evaluated.<>
