If you know mainframes, this book will help you extend your expertise to UNIX environments. This book is a quick, complete reference guide - and a powerful tutorial - for any mainframe professional who wants to understand UNIX and TCP/IP. It provides an overview comparing and contrasting mainframe and UNIX environments from the standpoint of the mainframe professional. It introduces mainframers to UNIX data and file handling methods; shows how UNIX provides for the commands and utilities mainframe programmers are familiar with; and discusses UNIX alternatives to mainframe JCL. It covers advanced UNIX shell scripts; UNIX editors; UNIX account configuration; and third-party tools that may make mainframe developers more comfortable in the UNIX environment. The book includes detailed lists of error messages, codes, UNIX signals, hints and techniques; conversion tables for ASCII and EBCDIC; an overview of the UNIX C Shell and TCP/IP, and much more. All mainframe programmers, analysts, system analysts and consultants who need to learn UNIX. This including the rapidly increasing number of programmers in IBM environments working with mainframes as network hubs, or with IBM RS/6000 workstations.
