During the past decade use of digital computers in civil engineering has progressed in amount of use and in ease of use. The advent of the Problem-Oriented Language (POL) was of tremendous importance to the profession, but the method of implementing processors for POLs was for some time a stumbling-block to the proliferation of the languages. In 1966, the writers (with S. J. Fenves) published a paper describing a new approach to the implementation of POLs, an environment which promised to simplify the production of processors and encourage the creation of POLs for many phases of civil engineering. The environment has now been in use for approximately four years, in various forms, from a prototype batch-mode version to a conversational, real-time, time-share version. The present paper is a progress report on the status of the environment for POLs (both proposed and actual) and the experience gained in this endeavor.
