All of the information about PEARL which is used in this report was obtained from the PEARL Language Description ESG-76. Work on PEARL Process and Experiment Automation Realtime Language was begun in 1968. The language was designed to provide systems engineers with a high level means of specifying programs for embedded applications. For that reason it emphasizes the areas of input-output specification and realtime processing and avoids many of the more complex and powerful constructs and capabilities of high level programming languages. In this latter, algorithmic aspect it has the appearance of a severely restricted dialect of PLI. It is the conclusion of this report that PEARL is not a viable candidate for the DoD common programming language effort, but that the experience gained from its unique approach to input-output specification and realtime control should prove valuable to the forthcoming design efforts.
