What is Mainframe Refresher?
Mainframe Refresher is a book written by Muthu, a mainframe expert with over 20 years of experience in the field. The book is divided into two parts: Part 1 covers COBOL, and Part 2 covers JCL. COBOL (Common Business Oriented Language) is a programming language that is widely used for business applications on mainframes. JCL (Job Control Language) is a scripting language that is used to control the execution of programs and tasks on mainframes.
A brief introduction to the book and its author
The book was first published in 2007 and has been updated several times since then. The latest edition of the book is based on IBM COBOL for OS/390 V2R2. The book contains over 300 pages of information, examples, exercises, and tips on mainframe programming. The author, Muthu, is a senior software engineer who has worked on various mainframe projects for clients such as IBM, Citibank, GE, and Verizon. He has also taught mainframe courses at several institutes and colleges.
The main topics covered in the book
The book covers the following topics in detail:
The basics of COBOL syntax, data types, variables, constants, operators, expressions, statements, and control structures.
The advanced features of COBOL such as tables, arrays, subroutines, functions, pointers, files, records, sorting, merging, searching, indexing, and report generation.
The fundamentals of JCL syntax, parameters, keywords, symbols, statements, procedures, steps, utilities, commands, datasets, libraries, catalogs, and spooling.
The practical applications of JCL such as creating jobs, submitting jobs, monitoring jobs, debugging jobs, handling errors and abends (abnormal ends), manipulating data sets (creating, deleting, renaming, copying, merging, splitting, etc.), performing backup and recovery operations, and executing system utilities (such as IEBGENER, IEBCOPY, IEBEDIT, IEFBR14, IDCAMS, SORT, etc.).
