Book description

This IBM Redbooks publication describes additional or advanced techniques for using FLEX-ES (a product of Fundamental Software, Inc., Fremont, California) with z/OS and various z/OS packages. Basic installation and use of FLEX-ES is described in EFS on a Linux base; Getting Started, SG24-7007. Both books are intended primarily for members of the IBM S/390 PartnerWorld for Developers (PWD) organization and for internal IBM users of the ITSO/EFS package.
