Learn mainframe and COBOL was like exploring space and time
back to the past , as in timemachine movie(one of my
favorite movies) and Men In Black 3 (pretty good
movie,funny too) ,but it remains something
new for me and I like something new 🙂
My learning spirit appears again,
this blog post appears after so long my hibernation in deep river -_-
What is a mainframe ?
After I read from several references can be summed up briefly mainframe is a multiuser computers that can be used to process bulk/batch transactions. The mainframe is products from IBM. This mainframe that I read, it using z / OS , the operating system that I never look it, but I ever hear it when I was studying history of Operating System :v
What is a COBOL ?
COBOL is a programming language used to make a program on the mainframe .
Why should COBOL ?
Because here is that I will learn is COBOL , not others #keep spirit with cobol, I like COBOL, I love COBOL :3 *cobol doctrine :v
” COBOL is a language that was developed special programming for business . It actually can be used for a wide range of programs and programming problems , but it is most popular for handling traditional business activities . COBOL excels in accounting systems and related activities such as inventory control , retail sales tracking , contact management , commissions , payroll – the list is almost endless . It is the most widespread commercial programming language in use today . It is English – like and easy to read . This makes it very popular with nonprogrammers . Financial officers can frequently read a section of a COBOL program and understand what it is doing with figures , without having to rely on programmers to interpret the program for them . There is no doubt that COBOL is the most successful programming language ever . With an estimated 80 million lines of COBOL code in use just in the United States , it remains a key language of choice for business applications. “
It is written in book that I get a book with a good cover and with title : ” COBOL in 21 days”,
Yeah I like that book cover, because same with my shio = > tiger :D.
