Explore the fundamentals of COBOL and Mainframe programming, the backbone of many key applications today, especially in the finance sector. This path guides you from basic COBOL syntax and data types to advanced data management, control structures, and file handling.
What you'll learn
Write basic COBOL programs using standard syntax and program structure
Define and manipulate strings, signed integers, and decimal values
Organize related data using group items
Perform arithmetic operations in COBOL programs
Implement decisions and loops with IF, EVALUATE, and PERFORM structures
Store and retrieve records using COBOL file operations
