History
OLIVER was written in 1972 by Ken Dakin, an independent CICS specialist (who also later produced SIMON (Batch Interactive test/debug), in response to a lack of suitable interactive debugging features in CICS. At the time, most CICS applications were written in IBM Basic assembly language and CICS had no features to prevent storage violations. As a result, errors in application programs frequently caused full CICS dumps and aborted the CICS session for all users. As more customers began using both COBOL and PL/I applications, the software supported these both at the assembly level and at source level from information collected at compile time.
Both OLIVER and SIMON were integrated with Viasoft Inc.'s static analyzer "VIA/Insight" to form the product "VIA/SmartTest", in the late 1980s. The combined product provided additional functionality to COBOL programmers, and the product is still in use at many IBM mainframe sites worldwide today, and is now (2012) distributed by Allen Systems Group as "ASG-SmartTest".

Famous quotes containing the word history:
“Three million of such stones would be needed before the work was done. Three million stones of an average weight of 5,000 pounds, every stone cut precisely to fit into its destined place in the great pyramid. From the quarries they pulled the stones across the desert to the banks of the Nile. Never in the history of the world had so great a task been performed. Their faith gave them strength, and their joy gave them song.”
—William Faulkner (1897–1962)
“It may be well to remember that the highest level of moral aspiration recorded in history was reached by a few ancient Jews—Micah, Isaiah, and the rest—who took no count whatever of what might not happen to them after death. It is not obvious to me why the same point should not by and by be reached by the Gentiles.”
—Thomas Henry Huxley (1825–95)
“I believe that history has shape, order, and meaning; that exceptional men, as much as economic forces, produce change; and that passé abstractions like beauty, nobility, and greatness have a shifting but continuing validity.”
—Camille Paglia (b. 1947)
