The present invention includes an interpreter in which a parser examines a message using grammar and lexical tables to produce a parse table. The parse table is compared to data needed in a semantics table to fire a rule. The firing of a rule causes a function table to be evaluated. The function table includes function calls which can perform user desired functions. Among the functions is a generate function which will take the contents of a table and turn it into a message and route the message to a destination where the destination can be a table, process or device. Plural interpreters can be created where each interpreter includes a workspace containing the above-mentioned tables. Each interpreter can perform a different task such as recognizing the meaning of a message in one language and performing some action such as sending out a message in a different language or updating a database. The present invention is particularly suitable for managing a machining workcell including machines from different vendors.
