Publisher's Synopsis
Written by authors who design, program and manage online systems supported by VSAM data sets, this text is intended to train readers - particularly business data processing programmers - to use VSAM in a practical manner. The VSAM key sequenced data set techniques required to operate productively in the business data processing environment are covered thoroughly. The text also illustrates tools in documented source code form - computational CLISTs, programs that read LISTCATs and automatically extract and analyze them, and prime or alternate key value distribution analysis routines (diskette available for uploading to mainframe). The management of VSAM data sets in the production environment is also addressed.
