CCOOBBOOLL -- DDAATTAABBAASSEE IINNTTEERRFFAACCEE http://www.tutorialspoint.com/cobol/cobol_database_interface.htm Copyright © tutorialspoint.com As of now, we have learnt the use of files in COBOL. Now, we will discuss how a COBOL program interacts with DB2. It involves the following terms: Embedded SQL DB2 Application Programming Host Variables SQLCA SQL Queries Cursors Embedded SQL Embedded SQL statements are used in COBOL programs to perform standard SQL operations. Embedded SQL statements are preprocessed by SQL processor before the application program is compiled. COBOL is known as the Host Language. COBOL-DB2 applications are those applications that include both COBOL and DB2. Embedded SQL statements work like normal SQL statements with some minor changes. For example, that output of a query is directed to a predefined set of variables which are referred as Host Variables. An additional INTO clause is placed in the SELECT statement. DB2 Application Programming Following are rules to be followed while coding a COBOL-DB2 program: All the SQL statements must be delimited between EXEC SQL and END-EXEC. SQL statements must be coded in Area B. All the tables that are used in a program must be declared in the Working-Storage Section. This is done by using the INCLUDE statement. All SQL statements other than INCLUDE and DECLARE TABLE must appear in the Procedure Division. Host Variables Host variables are used for receiving data from a table or inserting data in a table. Host variables must be declared for all values that are to be passed between the program and the DB2. They are declared in the Working-Storage Section. -

10 Programming Languages You Should Learn Right Now by Deborah Rothberg September 15, 2006 8 Comments Posted Add Your Opinion
10 Programming Languages You Should Learn Right Now By Deborah Rothberg September 15, 2006 8 comments posted Add your opinion Knowing a handful of programming languages is seen by many as a harbor in a job market storm, solid skills that will be marketable as long as the languages are. Yet, there is beauty in numbers. While there may be developers who have had riches heaped on them by knowing the right programming language at the right time in the right place, most longtime coders will tell you that periodically learning a new language is an essential part of being a good and successful Web developer. "One of my mentors once told me that a programming language is just a programming language. It doesn't matter if you're a good programmer, it's the syntax that matters," Tim Huckaby, CEO of San Diego-based software engineering company CEO Interknowlogy.com, told eWEEK. However, Huckaby said that while his company is "swimmi ng" in work, he's having a nearly impossible time finding recruits, even on the entry level, that know specific programming languages. "We're hiring like crazy, but we're not having an easy time. We're just looking for attitude and aptitude, kids right out of school that know .Net, or even Java, because with that we can train them on .Net," said Huckaby. "Don't get fixated on one or two languages. When I started in 1969, FORTRAN, COBOL and S/360 Assembler were the big tickets. Today, Java, C and Visual Basic are. In 10 years time, some new set of languages will be the 'in thing.' …At last count, I knew/have learned over 24 different languages in over 30 years," Wayne Duqaine, director of Software Development at Grandview Systems, of Sebastopol, Calif., told eWEEK. -
Instructions to the Ada Rapporteur Group from SC22/WG9 For
Work Programme of ISO/IEC JTC1/SC22/WG9 (Ada) For presentation to the SIGAda Conference December 2003 Jim Moore, [The MITRE Corporation] Convener of ISO/IEC JTC1/SC22/WG9 In this presentation, Jim Moore is representing his opinions as an officer of ISO/IEC JTC1/SC22/WG9. His opinions do not necessarily represent those of The MITRE Corporation or any of its sponsors. Goal for the Presentation A quick description of international standardization. An overview of the work programme of the standards committee responsible for Ada. A description of the process and constraints for amending the Ada language standard. Who Makes Standards? De jure standards are formal standards made Today’s by organizations authorized, in some way, to Subject make them. Examples include ISO and IEEE standards. De facto standards (more properly called specifications) are those recognized by the marketplace as important. Examples include OMG CORBA, Windows API.

About half of them are accredited by ANSI, allowing them to participate in international standardization activity.

Synchronizing Threads with POSIX Semaphores
3/17/2016 POSIX Semaphores Synchronizing Threads with POSIX Semaphores 1. Why semaphores? 2. Posix semaphores are easy to use sem_init sem_wait sem_post sem_getvalue sem_destroy 3. Activities 1 2 Now it is time to take a look at some code that does something a little unexpected. The program badcnt.c creates two new threads, both of which increment a global variable called cnt exactly NITER, with NITER = 1,000,000. But the program produces unexpected results. Activity 1. Create a directory called posixsem in your class Unix directory. Download in this directory the code badcnt.c and compile it using gcc badcnt.c -o badcnt -lpthread Run the executable badcnt and observe the ouput. Try it on both tanner and felix. Quite unexpected! Since cnt starts at 0, and both threads increment it NITER times, we should see cnt equal to 2*NITER at the end of the program. What happens? Threads can greatly simplify writing elegant and efficient programs. However, there are problems when multiple threads share a common address space, like the variable cnt in our earlier example. To understand what might happen, let us analyze this simple piece of code: THREAD 1 THREAD 2 a = data; b = data; a++; b--; data = a; data = b; Now if this code is executed serially (for instance, THREAD 1 first and then THREAD 2), there are no problems. However threads execute in an arbitrary order, so consider the following situation: Thread 1 Thread 2 data a = data; --- 0 a = a+1; --- 0 --- b = data; // 0 0 --- b = b + 1; 0 data = a; // 1 --- 1 --- data = b; // 1 1 So data could end up +1, 0, -1, and there is NO WAY to know which value! It is completely non- deterministic! http://www.csc.villanova.edu/~mdamian/threads/posixsem.html 1/4 3/17/2016 POSIX Semaphores The solution to this is to provide functions that will block a thread if another thread is accessing data that it is using. -
The Evolution of Lisp
1 The Evolution of Lisp Guy L. Steele Jr. Richard P. Gabriel Thinking Machines Corporation Lucid, Inc. 245 First Street 707 Laurel Street Cambridge, Massachusetts 02142 Menlo Park, California 94025 Phone: (617) 234-2860 Phone: (415) 329-8400 FAX: (617) 243-4444 FAX: (415) 329-8480 E-mail: [email protected] E-mail: [email protected] Abstract Lisp is the world’s greatest programming language—or so its proponents think. The structure of Lisp makes it easy to extend the language or even to implement entirely new dialects without starting from scratch. Overall, the evolution of Lisp has been guided more by institutional rivalry, one-upsmanship, and the glee born of technical cleverness that is characteristic of the “hacker culture” than by sober assessments of technical requirements. Nevertheless this process has eventually produced both an industrial- strength programming language, messy but powerful, and a technically pure dialect, small but powerful, that is suitable for use by programming-language theoreticians. We pick up where McCarthy’s paper in the first HOPL conference left off. We trace the development chronologically from the era of the PDP-6, through the heyday of Interlisp and MacLisp, past the ascension and decline of special purpose Lisp machines, to the present era of standardization activities. We then examine the technical evolution of a few representative language features, including both some notable successes and some notable failures, that illuminate design issues that distinguish Lisp from other programming languages. We also discuss the use of Lisp as a laboratory for designing other programming languages. We conclude with some reflections on the forces that have driven the evolution of Lisp. -
GNU Cobol FAQ
GNU Cobol FAQ | Status This is a 2.1 work in progress release of the GNU Cobol FAQ. Sourced at gcfaqrrst. Courtesty of ReStructuredText, Sphinx and Pygments. GNU Cobol 2.1 is not currently rolled out, but is available for testing. GNUCobolFAQppdf is also available, but broken, as a work in progress, with no work done yet, using Texlive and Sphinx. This FAQ is more than a FAQ and less than a FAQ. Someday that will change and this document will be split into a GNU Cobol manual and a simplified Frequently Asked Questions file.
