• RPG IV Style - Improving Performance With Algorithms, Part I - In this article and the next, I continue the discussion of algorithms by looking at how they affect the performance of your programs.
• In This Issue -
• Letters -
• IT Is Business Is IT - Robert Tipton says executives blinded to the importance of IT will find themselves just as lost as IT professionals who don't put business needs first.
• NetWare, We Hardly Knew Ye - NetWare the boot. Roger Pence tells why and what we might learn from IBM's decision.
• Logical Partitioning: Divide and Conquer - Frank Soltis tells you how you will be able to take advantage of server consolidation with V4R4's new LPAR capability, which lets you divide your SMP AS/400 into multiple, logically separate systems.

• Rochester Readies Java Server Benchmark - Pam Jones says IBM is eager to show off the AS/400's JVM in a transaction-oriented environment.
• Happy New Euro! - According to Benoît Herr, Europe's conversion to a single currency promises even greater headaches than the Y2K bug for companies and their IS departments around the globe.
• Infrastructure for E-Commerce - Nahid Jilovec says that companies who want to conduct dynamic, realtime e-commerce must change their system infrastructures to integrate data across applications and environments.
• Leaving the Fellowship of the Ring - Mel Beckman invites you to step into the world of Ethernet. At up to 1 Gbps, Ethernet is currently faster than Token-Ring, and products abound. Mel shows you how to migrate from Token-Ring to Fast or Gigabit Ethernet.
• "Switching" to Fast Ethernet - As enterprise LAN applications become increasingly bandwidth hungry, traditional 10BaseT broadcast-oriented networks bog down. Mel Beckman shows how high-speed Ethernet switching lets you speed up an existing slow network while improving reliability.
• NAT Conserves IP Addresses - Do your part - conserve Internet addresses! John Enck explains how Network Address Translation (NAT) lets multiple systems on a LAN share one or more IP addresses when accessing the Internet.
• Give Your Trigger Programs "Caller ID" - Lloyd Deviney presents RPG IV module CallerID, which you can bind to your trigger programs to find out which program caused a database change.
• Creating User Interfaces in Java: Components, Containers, and Layout Managers - You may end up doing most of your interface design work with a Java integrated development environment, but it's a good idea to know the basics of coding interfaces by hand with the Abstract Windowing Toolkit. IBMers George Farr and Phil Coulthard begin showing you how in this Java for RPG Programmers article.
• V4R3 Backup and Recovery Enhancements: More Help Is on the Way - M.J. Thompson and Jerry Simon show you how the latest V4 enhancements make protecting your AS/400 data simple and convenient.
• Eye on SNA Gateways: eNetwork Communications Server for Windows NT and SNA Server - Jim Hoopes gives an overview of two competitive SNA Windows 95/NT gateways - IBM's eNetwork Communications Server and Microsoft's SNA Server - and steps through configuring a basic AS/400 connection with each product.
