6. The prototype
</SectionTitle>
    <Paragraph position="0"> The project which resulted in the design of Word Manager was started at the beginning of 1986. Since then, several prototypes were made, most of which implemented parsers for various parts and versions of the formalism, and the user interface for the 'interactive specification environment' shown in Figure 5. In the earlier phases of the project, three different machines were employed: the first was a Sun 3/50, which was primarily used in conjunction with the parser generator tools LEX and YACC. The second was a Lisp machine of the Texas Instruments Explorer family, which was used to prototype user interfaces. The third was an Apple Macintosh II. This machine became available towards the end of 1987, when the design of both the formalism and the 'specification environment' were in a state which suggested their full implementation. The following two years were spent on this task, which resulted in a prototype that includes about 16,000 lines of code (most of it written in Object Lisp (ALLEGRO 1987), an extension of Common Lisp). Notice that this prototype does not include the DBMS, though it provides the full functionality of the 'specification environment;' since the operating system did not provide., interprocess communication, it was impossible to realize the network architecture proposed in Figure 5. In order to complete the system, we have therefore switched back to a UNIX environment, i.e.</Paragraph>
