Getting Started with Mainframe COBOL

This course serves as an introduction to programming in COBOL, especially on the Mainframe, through use of a real-world example program.

COBOL seems to have more lives than a herd of cats. The death of COBOL has been touted for years - nay, decades. Yet, according to some estimates, there are well over 200 BILLION lines of COBOL code out there - and more code is being generated every day. In this course, Getting Started with Mainframe COBOL, you will learn many of the basics of the oft underestimated language that is COBOL by using it to solve a real-world business request. First, you'll learn all about the history of COBOL. Next, you'll explore the COBOL program structure. Finally, you'll wrap up this course by learning about data types and then trying your hand at writing a real-world COBOL program. By the end of this course, you'll understand the basics of COBOL, including being able to successfully write your own programs.

Reviews summary

Foundational mainframe cobol introduction

According to students, "Getting Started with Mainframe COBOL" provides a largely positive and excellent foundation for those new to this specialized programming language. Learners particularly praise the course for its clear and concise explanations of COBOL concepts and its focus on a practical, real-world example program, which is highly beneficial for understanding application. The instructor's knowledge and teaching style are frequently highlighted as a major strength, making a potentially complex subject accessible. While the course is ideal for absolute beginners, some more experienced programmers note it might lack the depth for advanced topics, suggesting it's important to set expectations. A few learners also mentioned that hands-on practice with a mainframe environment could be challenging to arrange independently.

Instructor's expertise and teaching style are highly praised by students.

"The instructor's deep knowledge of COBOL and mainframes shines through every lesson."

"Their explanations were insightful and made the seemingly dry topic of COBOL engaging and understandable."

"I found the instructor very patient and thorough in explaining concepts, which was extremely helpful."

Emphasizes a real-world example, highly valuable for practical application.

"The real-world example program was the strongest part of the course for me, showing practical COBOL usage."

"Applying COBOL to a business request made the learning truly relevant and helped the concepts stick."

"I gained confidence by seeing how COBOL is used in actual mainframe scenarios, which is essential for my career."

Provides a solid and accessible introduction for new COBOL learners.

"The course breaks down complex COBOL concepts into digestible lessons, making it less intimidating for beginners."

"It really helped me get started without feeling overwhelmed by the mainframe environment and COBOL syntax."

Some learners faced hurdles with environment setup or sought more practical labs.

"Accessing a mainframe environment for hands-on practice was a bit of a challenge on my end."

"I wished there were more guided hands-on labs or exercises to reinforce the coding lessons."

"While the program example was good, I needed more opportunities to write my own COBOL code myself to feel proficient."

Primarily suited for absolute beginners; may lack depth for experienced coders.

"If you already know some COBOL, this course might feel a bit slow and basic for your needs."

"I was hoping for more advanced topics, but it really is a strict 'getting started' course as titled."

"It's a great intro, but don't expect to become a mainframe expert overnight, it's just the first step."
