An Advanced Course Using 1974 or 1985 ANS Cobol (Pt. 2) (Structured ANS Cobol) - Tapa blanda

Reseña del editor

This 2-part course is the easiest way for you to learn what you want to know about ANS COBOL, whether you're developing new programs or maintaining old ones. The two parts are independent: you can choose either or both, depending on your current skills.Part 1: A Course for Novices teaches beginners how to design and code COBOL programs that prepare reports. Because report programs often call subprograms, use COPY members, handle one-level tables, and read indexed files, this book covers those subjects, too.Part 2: An Advanced Course is a complete guide to the 1974 and 1985 elements that all programmers should know how to use (although many don't). So it covers: sequential, indexed, and relative file handling...alternate indexing and dynamic processing...internal sorts and merges...the COPY library...subprograms...single- and multilevel table handling...character manipulation...and, if you're working on a 1974 compiler, proper use of 1974 code so your programs will be easy to convert when you switch to a 1985 compiler.Alone or together, I'm convinced you'll find these books to be the most effective COBOL course you've ever used.
