The COBOL language enables mainframe program development! Can C be used to develop mainframe program

1. The COBOL language can develop mainframe programs, but the C language cannot. The C language can develop microcomputer programs, and C is mainly used to learn software development ideas. Mainframe programming is basically developed in the COBOL language.

2. Because the mainframe is developed in combination with COBOL, COBOL is inseparable from the mainframe, and the mainframe is inseparable from COBOL

COBOL (Common BusinessOrientedLanguage) was the first widely used high-level programming language. In business management, numerical calculations are not complicated, but the amount of data processing information is huge. In May 1959, the Pentagon commissioned a committee headed by Dr. Grace Hopo, developed under the auspices of Rearadmiralgracehopper, and published in 1961 by the American Association for the Language of Data Systems.

After continuous revision, enrichment, improvement and standardization, it has been developed into a variety of versions.

COBOL focuses on the handling of data items and input and output records, and provides a simple way to handle files with large amounts of data. As you can see from the name, it is mainly used to solve a large number of data processing problems in the fields of business and enterprise management, and is also known as enterprise management language, data processing language, etc. The development of the COBOL language began in the late 50s, when the production of computers had entered the second generation, and the field of computer applications began to expand from numerical computing to data processing.

The amount of data that needs to be processed in the management of business and corporate transactions has increased dramatically, and there is an urgent need for programming languages suitable for this area to improve the quality and speed of programming. It is in this social context that the COBOL language came into being. In other words, COBOL is over half a hundred years old.

COBOL was officially released in April 1960 as COBOL 60. Now the latest version should be COBOL 2002, and it is still being improved, and the future COBOL will support new technologies in the web era such as XML. In other words, COBOL will continue to develop and apply, but compared with C or Fortran, COBOL's numerical and logical operations are weaker.

C language is OK, software on a computer can be developed in C in addition to BIOS, UNIX is developed in C!

First, the COBOL language can be used, the C language can develop minicomputer programs, and the C language is mainly to learn the software development ideas.

Second, mainframe program development is basically in the COBOL language.

Third, because the mainframe is developed in combination with COBOL, COBOL is inseparable from the mainframe, and the mainframe is inseparable from COBOL

Cobol is a relatively simple language that is not a problem to learn, but most of the Cobol programs are now mostly only run on IBM Mainframe, and some are on Unix, but very few.

So to learn this thing you must have some understanding of the IBM mainframe system, that is, z os or OS 390, you can go to the IBM official website to find some technical documents, tell you some keywords, these are the more important things in the OS 390 system:

MVS, VSAM, JCL, DB2 for z OS, IMS (older hierarchical databases, still used in some banking systems), CICS, IBM WebSphere MQ for z OS, REXX, TSO, ISPF, etc.

In addition, you can build the next z os virtual machine on your own PC, as far as the beginner introductory learning is concerned, there are still a lot of things in it.

IBM host development mainly needs to learn, TSO ISPF, COBOL, JCL, DB2 and CICS, the recently published new book "IBM Host Technology in a Nutshell" systematically introduces this knowledge, and provides a lot of practical program examples, for readers' reference, this is a book that really makes your IBM host technology not ask for people.

HSBC is okay, it is normal to train for two months, although COBOL has a narrower employment area, but the salary is indeed much higher, and it is easier to jump after HSBC comes out, and now many people who have worked for several years want to enter HSBC.

It seems to be 14 months' salary, and if it is a project in Europe and the United States, it is quite easy, and there is very little overtime, and the Asia-Pacific project is more tiring.

I'm doing cobol here at Citi in Shanghai... I also just graduated this year. It's almost every day of overtime.,I really can't afford to be sad.。。 Generally, it will definitely be more than 10,000 in about 3 years. . .

Eh: Are you also Wensi? 2 months in Wuhan and 2 years in Guangzhou?

1.The mainframe is mainly used for the first bank, the financial industry such as the first exchange. Acts as a server to store and process data.

It has strong processing power and high security performance. However, due to the high price, generally 20 million US dollars, it is difficult for the average company or school to have sufficient funds to buy.

2.Mainframe languages I know of have cobol. The mainframe operating system is generally Z OS, which is a series of operating systems based on the Z Artitecture system architecture.

3.At present, there is a shortage of mainframe talents in China, because of the wide knowledge required for mastering the mainframe, and the content learned is very different from the language of the open platform, and furthermore, there is no relatively formal and powerful training institution in China to do relative training, so there are almost only a handful of mainframe talents in the world.

4.In the next few decades, the mainframe will be difficult to obsolete, it is a product of IBM, a product of closed research, or promising, if you master it.

The two standards that came out in '74 and '85 were used more. It seems that most of the ANSI COBOL is, if it is a new mainframe, it may be the standard that came out in 2002, and it is not too clear, you see what standard the mainframe you want to understand!

I think there are more cobol85s.

MF is short for mainframe, and COBOL is a mainframe program**.

MF is generally used for banking, insurance, etc. Today's MF machines generally use IBM and HP mainframes. The program that runs for the MF mainframe is developed in the COBOL language.

But COBOL is just a program, and a collection of programs and programs can form a business flow. Therefore, MF also needs JCL or shell to execute the program in series.

COBOL: The most widespread programming language in the field of data processing.
