How can I learn COBOL without knowing any programming language?
If you have fair idea on JCL, VSAM, FIle creation using option 3.2 and IBM Utilities like IEBGENER, then it will help you to understand COBOL better but this is not mandatory and you can still learn COBOL easily without any prior understanding of any programming language. Would you like to learn TSO-ISPF?
