The programming language PEARL (Process Experiment AutomationRealtime Language) is designed as a universal realtime language, in which all important realtime and process programming features are integrated as equal language elements in addition to the commonly used options for describing data and algorithms
. Therefore, PEARL is suitable for both commercial and technical applications. The PEARL programming language was formulated jointly by process computer manufacturers and users from research institutes in the 1970s. About 25 institutions were involved in its development. PEARL is a programming language that supports the development of very large programs
. Thealgorithmic language resources of PEARL are not very different from those of other higher-level languages. The algorithmic language concept is based mostly on Algol 68 and was influenced by Pascal. The syntax was largely adapted to PL/1.task with agreements is shown in the example.
