Development toolsBecause COBOL programs generally run on large hosts, and large host resources are rare, beginners do not have so many opportunities to practice the program directly above. But it's hard to think of someone who really wants to learn. Here I offer several workarounds (only under Windows).Recommendation: Opencobolide is an

Recently I have been busy with my work and my graduation work, so I am not very busy. Now we have a bit of free time. Let's take a look. Since so many people need the COBOL teaching materials, I will recommend them to you.It is in the IBM library, and I think it is comprehensive. As long as you finish reading this, it should be okay with Cobol. IBM Library ReaderHttp://www-1.ibm.com/support/docview.wss?

I have recently started learning Cobol. Of course, I need to understand some background and application fields and prospects for learning a language. Let's talk about my questions and understanding. 1. How old is Cobol?For this question, read a book and check the information. COBOL is the abbreviation of common business oriented language. It is mainly used to s

I really didn't expect that I would do it in COBOL, even if I knew the history of computers: Post a post that has been transferred n times 1.

Abbreviations: COBOL(Common Business Oriented Language) Chinese Translation: Cobol Language Interpretation: a programming language similar to English that is suitable for business and data processing. This language accurately expresses the business data processing process. COBOL is one of the oldest advanced programming languages and the first commercial languag

The first time I got in touch with Cobol today, the lecturer was an English speaker. It was really hard to take the course. Alas .... the English is not good. There are two books in China that feel okay, the simple guide of COBOL and the programming language design of COBOL (TAN haoqiang) The following is the first program and a hello program. The tool is First

Interest calculation is an important business of banks, including daily proxy customer collection, calculation of customer interest, and annual interest calculation. Currently, most of this work is performed on the Safe Application System Platform of the IBM es9000 host. The online program and the on-line interest rate program are implemented in the IBM 370 assembly language. For ease of reading and writing in assembly language, the data storage format is defined in the data stored in the VSAM f

Next to the book (an entry to the COBOL study notes)SlaveProgramWe can see that the COBOL program is divided into four parts:Identification Division.Environment Division.Data Division.Procedure division. For more information about the functions of each part, see Chapter 1 Cobol. Here we mainly look at the content in procedure Division. This is the core.Process

The format of the COBOL source program is as follows: Each line starts with a sequence number with six characters. You can enter limit 10 or limit 20 to indicate the rows. The sequence number area is followed by an indicator area of a character (7th characters), as shown in the first line. You can use "*" and "/" to represent comments, "_" to represent continued rows, and "D" to represent debugging. The indicator area is followed by four characters (8
