The Bureau's overall goal is to strengthen and advance the Nation's science and technology and facilitate their effective application for public benefit. To this end, the Bureau conducts research and provides: (1) a basis for the Nation's physical measurement system, (2) scientific and technological services for industry and government, (3) a technical basis for equity in trade, and (4) technical services to pro- mote public safety. The Bureau consists of the Institute for Basic Standards, the Institute for Materials Research, the Institute for Applied Technology, the Institute for Computer Sciences and Technology, the Office for Information Programs, and the Office of Experimental Technology Incentives Program. THE INSTITUTE FOR BASIC STANDARDS provides the central basis within the United States of a complete and consist- ent system of physical measurement; coordinates that system with measurement systems of other nations; and furnishes essen- tial services leading to accurate and uniform physical measurements throughout the Nation's scientific community, industry, and commerce.

  • 16520: Application Development for Z/OS - Not Your Father's Green Screen
    16520: Application Development for z/OS - Not your Father's Green Screen Rosalind Radcliffe Distinguished Engineer, IBM Academy of Technology Member IBM Corporation [email protected] @RosalindRad Insert Custom Session QR if Desired. Abstract Ask most people how they write and maintain applications on z/OS and you hear "oh, you use this thing called a green screen" followed by a chuckle. In reality, application development for zEnterprise applications has been transformed over the past several years to the point where application developers enjoy the same or better features from integrated development environments as programmers who work on other platforms. Advances in remote system communication and interaction, syntax- highlighting, parsing, and code understanding for Assembler, PL/I, C/C++, and COBOL source code, as well as programming assists such as code snippets and templates are all available to application programmers. Interactive debug of applications, written in multiple programming languages and running in various runtime environments is also possible and can greatly boost programmer productivity. Come and learn about how these features can enable application developers who are new to the mainframe to interact with, update, and efficiently enhance mainframe applications. 16721: Decision Management: Making the Right Change, at the Right Time 3/4/15 3 IBM DevOps point of view Enterprise capability for continuous software delivery that enables organizations to seize market opportunities and reduce time to customer feedback Continuous

  • Mainframe to Enterprise to the Is Curriculum
    https://doi.org/10.48009/2_iis_2012_182-192 Issues in Information Systems Volume 13, Issue 2, pp. 182-192, 2012 MAINFRAME TO ENTERPRISE TO THE IS CURRICULUM Joseph Packy Laverty, Robert Morris University, [email protected] Frederick G. Kohun, Robert Morris University, [email protected] John Turchek, Robert Morris University, [email protected] David Wood, Robert Morris University, [email protected] Daniel Rota, Robert Morris University, [email protected] ABSTRACT Over the decades the concept of a mainframe has been synonymous to IBM operating systems and the COBOL programming language. While object-orientated programming languages, web interface transaction systems, web services, distributed services, and mobile application topics are frequently included in the IS/CS curriculum, this paper considers the inclusion of IBM Enterprise Systems. IBM zEnterprise has evolved into an integrated, scalable, enterprise system which supports legacy applications, open-source applications and tools, DB2, Cognos, SPSS, data mining and Rational project management tools. The growth and market penetration of IBM zEnterprise has been spectacular. This evolution of IBM Enterprise Systems provides many opportunities for IS/CS majors. A case study implementing the IBM Academic Initiative in an ABET-CAC curriculum is presented. KEYWORDS: IBM Academic Initiative, IS Curriculum, IBM zEnterprise, ABET-CAC, z/OS, COBOL, CICS, DB2, Open Source, Rational Application Developer for Z Systems, Robert Morris University, Marist College INTRODUCTION Over the decades the concept of a mainframe has been synonymous to IBM operating systems and the COBOL programming language [1]. In recent years, computer hardware evolved in various directions, e.g., desktop, blade servers, super computers and mobile devices.
