For years now the question has been surfacing in the OpenVMS community "Where are the pimply faced kids?" The other situation which seems to continually occur is a developer of one language suddenly finding themselves having to modify or maintain an application written in a language completely foreign to them.

This book was a year long effort to answer both of those questions. It also should help those to work on a good platform. Once the rudimentaries of logging in, symbols, logicals and the various editors are handled this book takes the reader on a journey of development using the most common tools encountered on the OpenVMS platform and one new tool making headway.

A single sample application (a lottery tracking system) is developed using FMS and RMS indexed files in each of the covered languages. (BASIC, FORTRAN, COBOL and C/C++). The reader is exposed on how to use CDD, CMS and MMS with these languages as well.

A CD-ROM is included which contains the source, MMS and command files developed through the course of the book. Once RMS has been covered with all of the languages the same application using MySQL with C and FMS is covered. This breaks readers into the use of relational databases if they are not currently familiar with the concept. Rounding out the technical portion of the book is the same application using RDB with FMS. While source code is provided for all of the language implementations only FORTRAN and COBOL are actually covered in the text.

It is the hope of the author that this book will prove a useful reference on the desk of every OpenVMS developer. The inclusion of MySQL should benefit both those unfamiliar with relational technology and those platform veterans interested in playing with MySQL for the first time.


There are two main intents of this book...
  1. Allow developers who know at least one of the covered languages on another platform to quickly come up to speed on the OpenVMS platform.
  2. Assist current OpenVMS developers finding themselves having to work with a differentlanguage on this platform.

Tips from the Book
Reviews:

"DO NOT begin any new database projects without first reading chapter 13 (MySQL) and chapter
14 (Oracle-RDB) of this book. Hint: while you can acquire MySQL for free, and it may have a place
for some small applications, it may cost you more in the long run."
Neil Rieck, OpenVMS Application Developer

"Hands-on programming throughout the book provides a highly effective learning tool, and the best practices, advice, and knowledge transfer from the author gives the reader the unique feeling that they are sitting down next to a mentor, being coached through the tricks of the trade!"
Regan Windsor, Reader Views

"I had it shipped to the Netherlands for the price of $96. It arrived within a week of the order date.  Worth every dollar (euro). "
Wilm Boerhout

"Highly recommended for OpenVMS programmers (especially those new to OpenVMS who need a good bootstrap). At the very minimum, a copy of this book should be purchased as an "office resource" in every location where OpenVMS developers work."
Neil Rieck, OpenVMS Application Developer

"Amazing.  This is a truly astonishing work and a MUST for everybody who is starting with application developing, be it on VMS or not (I can not tell for others as I am starting myself). It is not a book where you will find many theories about abstract topics but one displaying everything you need to know by means of examples, explaining each example's important parts in-depth. You really feel the experience of the author throughout the text! This is a book I'd try to take with me if my house was burning down."
Thierry Dussuet, OpenVMS Student

After I got over the surprise of seeing a new book on OpenVMS Software Development I wondered
at the title - this is an 800 page book with a CD! The book is intended for people who are familiar
with programming on another platform and are faced with maintaining an application on VMS
written using classic OpenVMS software tools. Perhaps a better title would be “What a person
unfamiliar with OpenVMS should know to maintain an OpenVMS application”.

Hughes describes uses of: the MMS and CMS tools from the widely used DECSET OpenVMS
software development toolkit; CDD; FMS; the RDB and MySQL databases. He also mentions other
tools often found in the OpenVMS application development environment such as VMSMAIL,
PHONE etc. Parts of OpenVMS which will be unfamiliar to a person transferring from another
platform, such as logical names and DCL symbols, are introduced as they will often be
encountered when maintaining an application on OpenVMS.

The book is based around a single application which is developed in each of DEC BASIC,
FORTRAN, COBOL, C and C++ using a variety of tools. Full source code is provided on the CD. By
repeatedly implementing the same thing in different languages the programmer familiar with one
language can learn about another. The presented code is not suitable for a production
environment but is intended to illustrate something being described in the text. For example the
error handling is not always fully implemented except when Hughes wishes to describe dealing
with errors.

Hughes describes building the application and typical ways of organizing the development
environment and highlights common pitfalls for programmers coming from other platforms. The
book is written in American English and in a casual style. Although it is easy to read some people
who are not native English speakers may not recognise some of the colloquial terms used. I don’t
think this will significantly hinder understanding.

Hughes has opinions about how things should be done and is not afraid to state them! Personally
I find an opinionated book easier to engage with because there is something to argue or agree
with. The final chapter is Hughes opinion on the state of the IT Industry.

The key to appreciating this book its specific focus. I think the target audience will find this a useful
resource to sit alongside the OpenVMS Documentation. However the material is also useful for an
OpenVMS developer faced with an application in a different programming language to the one they
usually use.
