How this Documentation Differs From Server Express 1.0

The documentation on this CD contains an updated version of the book set provided with Server Express 1.0. These HTML books contain new information on topics that are not applicable to earlier versions, and contain fixes for any errors identified in the original versions of the documentation. The changes contained in the HTML books are described in the following sections.

This document is cumulative, and lists changes since the original Server Express 1.0 documentation.

Topics Added or Updated at 2.0.11 Service Pack 1

The following topic was updated for Server Express 2.0.11 Service Pack 1:

• Debugging. An advanced remote debugging facility and a new way of controlling cross-session debugging were added. See the chapter Debugging Methods in your Debugging Handbook for further information.

• The Rebuild utility. This has been enhanced to improve performance. See the chapter Rebuild in your File Handling book for further information.

• File Handler. The default location for the configuration file has been changed, and the default setting for the configuration option READSEMA has been changed. See the chapter File Handler Configuration in your File Handling book for further information.

• Client/Server Binding. This topic has been moved from the Communications book to the Distributed Computing book. The Communications book has been removed from the documentation set. In addition, the Client/Server Binding environment variables MFCSCFG and MFLOGDIR have been added to Appendix A of your User's Guide.

• File status codes. These have been removed from the File Handling book. They are now documented in the Error Messages book only.

Topics Added or Updated at 2.0.11

The following topic was updated for Server Express 2.0.11:

• Additional facilities for using Java and COBOL components together in a distributed computing environment. On some platforms multiple JVMs are now supported. You can have parameters passed BY REFERENCE updated by the called program. You can pass Java data to COBOL data structures. See your Distributed Computing book for information about using Java and COBOL together.

The following topic was added to the books for Server Express 2.0.11, and is not relevant to earlier versions of Server Express:

• Using your own C-ISAM file handling routines. See your File Handling book for information on this topic.

Topics Added at 2.0.10

The following topic was added to the books for Server Express 2.0.10, and is not relevant to earlier versions of Server Express:

• Using Java and COBOL components together in a distributed computing environment. You can now call procedural COBOL from Java, call Object COBOL from Java, and call Java from Object COBOL. You can also call Java classes and methods from procedural COBOL using the Java Native Interface, and can generate an Enterprise JavaBean from a COBOL class. See your Distributed Computing book for information about using Java and COBOL together.

Topics Removed at 2.0.10

The following topic was removed from the books for Server Express 2.0.10:

• Support for Object Request Broker Technology. This was documented in the book ORB User's Guide

Topics Added at 2.0

The following topics were added to the books for Server Express 2.0, and are not relevant to earlier versions of Server Express:

• 64-bit programming. If your UNIX platform supports the execution of 64-bit applications, then Server Express 2.0 for that platform is installed with both a 32-bit version and 64-bit version of the Server Express development and run-time systems. This enables you to write programs that can be run on both 32-bit and 64-bit systems, and to migrate applications from 32-bit systems to 64-bit systems. The chapter Working in 32-bit and 64-bit Modes in your Server Express User's Guide describes how to use Server Express in 32-bit mode or 64-bit mode. The chapter Creating 64-bit Programs in your Programmer's Guide to Writing Programs describes how you create a 64-bit program.
  
  
• Prototyped library routines. The COBOL library routines now make use of CALL prototyping. For information, see the chapter Library Routines in your Programmer's Guide to Writing Programs.
  
  
• File Control Description (FCD) for 64-bit programming. See the chapter File Handler API in your File Handling book for a description of this FCD (known as FCD3).
  
  
• Licensing for 64-bit systems. See your Managing Application Server Licenses with AppTrack for Application Server licensing, and your License Management Facility Administrator's Guide for development system licensing.
  
  
• New options for the Header-to-COPY Utility. See the chapter Header-to-COPY Utility in your Programmer's Guide to Writing Programs.

Topics Added at 1.1

The following topics were added to the books for Server Express 1.1, and are not relevant to earlier versions of Server Express:

• FaultFinder Listing Generator, described in the chapter FaultFinder in your Debugging Handbook
  
  
• Scan64, described in the chapter Scan64 in your Debugging Handbook.
  
  
• COBOL BS2000 Dialect, described in the chapter Siemens BS2000 COBOL Syntax Support in your Language Reference - Additional Topics
