Cobol For The 21st Century 11th Edition Pdf Download

i had never used a programming language before, let alone a programming language as difficult as cobol. i was assigned the task of writing a program to print out a message when an error message was received in the mainframe. i was told that if i couldn’t do it, then it would have to wait for someone else. so, i began writing a program. the first thing i did was to write a main program. i then proceeded to write a separate program for each subroutine that was needed. the main program would call the subroutines. this is the way cobol programs are written. i didn’t have much experience in cobol but i was eager to learn.

i was told that i needed to learn how to use cobol. i was told to learn the language from a book. i couldn’t afford to buy a book. i went on a journey through the world of computers. after a year, i got a job at a company. i was given a manual which contained a book on cobol. i started studying the manual and the book. it seemed like a good book to work through.

in his book (and in the very first book i ever bought that was on cobol) bill reinke explains how one can go from a novice, to a professional after 15 years of work experience in the same programming environment. for example, the first time i coded in cobol, i used a text editor and compiled it on a vax-11/780. (in fact, i think that my first application compiled was an accounting package i wrote in 1984 that processed payroll for a small insurance company.) then, over the next 10 years i would move to a unix-based system. finally, i moved to a windows system. the question is: what will i be using in 15 years? will my first programming language be c#, java, or something else? will i have to learn a completely new environment? you can’t predict the future.

Writing COBOL Code in a Small Business or corporate context: COBOL can offer many benefits in terms of reducing development costs and improving IT efficiency. However, even if you’re a seasoned COBOL developer and you’re well aware of every rule and standard in the COBOL language, the vast majority of your needs could be met by cheaper, newer programming technologies. There is no doubt that the selection, construction and adoption of a modern development toolkit, like JBuilder, helps in rapidly deploying COBOL solutions. However, a well-used development toolkit may not always be the best long-term solution for an organization. Still, you need a good understanding of COBOL and how it operates, but only a select number of developers know COBOL inside-out. So why not use modern development tools to create your code and leverage the expertise of a dedicated team of COBOL developers? These experienced programmers will be able to help you evaluate the viability of advanced COBOL techniques like Object Oriented Programming (OO), CASE tools, specialized programming languages and modern development tools.
I had a friend who developed large COBOL code bases. She told me that. basically, even the most simple of things in COBOL can require 500 to 1000 lines of code. And many COBOL experts tend to tell you that. In my opinion, that is mostly based on what they have learned themselves, it is based on their knowledge about COBOL. Programming experts in COBOL will be more than a little uncomfortable with this statement but. Honestly. even I. could be wrong.
