Cobol learning made easy

Learn how COBOL programs are structured through divisions, sections, and paragraphs, with sentences and statements, and how to execute on a mainframe using a card.

Explore cobol theory part 2, detailing picture clauses, data storage, level numbers, and group item declarations, and how numeric, alphanumeric, and decimal values are represented in working storage.

Explore cobol theory part 4 by examining input and output, decimal truncation, syntax rules, memory basics, program naming, and case and quotation mark usage.

Revisit cobol theory topics, outlining the four divisions, environment, data, and procedure divisions, and explain copybooks, tables, memory allocation, and compiler behavior.

Explore how a COBOL program displays figurative constants, uses double quotes to define values, and compares results at compile and run time.

Explore how MOVE operates on alphanumeric data declarations in Cobol, showing truncation when moving from a larger to a smaller field, and how spaces are filled from the right.

Explore how the move operation handles numeric data declarations in cobol, comparing moving from smallest to largest versus largest to smallest and illustrating truncation rules that affect numeric values.

Master the move verb for one to many in Cobol by examining a program with multiple variables, display and redisplay logic, and timing considerations.

Master Cobol multiply and divide verbs through practical examples, understand how outputs and quotients are produced, and explore how these arithmetic verbs drive program results.

Explore if statements in COBOL through simple, self-explanatory examples. Learn how conditional logic governs program flow in COBOL.

Discover how nested if conditions control flow in COBOL, with a sample that checks if a value is less than 18 to classify as minor or major.

Learn to build a simple perform program in COBOL that collects a student record, inputs six subject marks, computes total, checks eligibility by grade ranges, and displays results.

Learn how a Cobol program demonstrates the cond level number 88 by evaluating marital status, salary, and related conditions, and displaying the results.

Master editing pic clauses in cobol, managing dollar signs, spaces, and numeric formats, while exploring loops and picture-driven data edits.

Demonstrates a simple COBOL program that performs a number of games and displays them three times in the display area with error-free compilation.

Explore how to perform thru in Cobol, and how statements are processed within a program.

Learn how to implement a single dimensional table program in Cobol, reading and writing values and exploring basic table concepts and multidimensional tables.

Learn to read a file in COBOL by running the program, handling input, and displaying specific entries as data moves through the process.

Explore how to call a subprogram in Cobol, including call by reference and call by content, and compare static versus dynamic calls in mainframe programs.

Apply inspect and replacing techniques to variables in cobol programs to manage data and character handling. See how replacing specific characters affects program behavior in a network.

Learn to join multiple small strings into a single string using a clear syntax with delimiters, and compare string segments to ensure correct concatenation.

Complete this Cobol course easily by going through all topics and revising them once or twice to solidify your understanding. Expect additional tutorials on mainframes.
