If you're a COBOL programmer who is just starting to work on an IBM mainframe, this book shows you how to work with VSAM files. These are mainframe versions of the sequential, indexed, and relative files of standard COBOL. To work with them on a mainframe, though, you need to use extensions to the standards; the IBM codes for error processing; JCL to run the programs that use the files; and Access Method Services (AMS) to set up the files. This book shows you to use them all.Lowe, Doug is the author of 'VSAM for the COBOL Programmer - Doug Lowe - Paperback' with ISBN 9780911625127 and ISBN 0911625127.
