Now LINC is known as Unisys Enterprise Application Environment (EAE) and builds applications by generating executable code (Cobol)for Unisys ClearPath systems, Dorado and Libra (formerly Burroughs A-Series & Sperry OS1100 mainframes), Microsoft Windows, and various Unix and Linux platforms. It will also generate GUI front-end clients in Java
OS 2200 provides a complete Java environment. [12] Java on OS 2200 has evolved from an interesting additional capability for small servlets and tools to a full environment capable of handling large applications. The Virtual Machine for the Java Platform on ClearPath OS 2200 JProcessor is a Linux port of the Oracle Corporation Java release.
The Symbolic Stream Generator (or SSG) is a software productivity aid by Unisys for their mainframe computers of the former UNIVAC 1100/2200 series. SSG is used to generate RUN-Streams (corresponding to IBM's Job Control Language ), apply and administer symbolic changes to program sources as a form of version control , and for many other purposes.
OS 2200 is the operating system for the Unisys ClearPath Dorado family of mainframe systems. The operating system kernel of OS 2200 is a lineal descendant of Exec 8 for the UNIVAC 1108 and was previously known as OS 1100.
COBOL programs are used globally in governments and businesses and are running on diverse operating systems such as z/OS, z/VSE, VME, Unix, NonStop OS, OpenVMS and Windows. In 1997, the Gartner Group reported that 80% of the world's business ran on COBOL with over 200 billion lines of code [c] and 5 billion lines more being written annually. [114]
Many instructions also perform very complex functions such as one that implements a large part of the COBOL EDIT verb. The above figure shows some of the building blocks of the architecture. "Data" and "COMM" are two of the primary examples of software subsystems that live in a protection ring between that of a user application and the Exec.
A number of intrinsic functions were inserted by the compiler to ensure the program and database used the same definition of database structures. Originally, DMSII maintained a data dictionary that the application programmer referenced in its source code. The source for the data structures was maintained in an ordinary CANDE source file. That ...
The early input scheme for the 4GL supported entry of data within the 72-character limit of the punched card (8 bytes used for sequencing) where a card's tag would identify the type or function. With judicious use of a few cards, the 4GL deck could offer a wide variety of processing and reporting capability whereas the equivalent functionality ...
