Customers and Partners, We’re Listening

Thank you for being a valued customer or partner of Cincom Smalltalk. As a customer or partner, do you know about the Cincom Smalltalk Resolutions Newsletter? This exclusive, subscription-only publication was created over a decade ago for customers and partners only and gives subscribers an easy way to scan through the resolutions that were delivered for Cincom Smalltalk during the previous month.

Over the years, feedback from customers and partners like you has allowed us to refine the newsletter into what it is today. After regular feedback from readers, our product marketing team stepped in to add more information for those requesting an easier way to track the happenings with Cincom and Cincom Smalltalk. Of course, we never want to distract from the original purpose of the Resolutions Newsletter, so product marketing adds top stories, technical and developer events, tips and techniques and other important web links. These links help you navigate our expansive website and give you ways to get in touch with our developers and product team. 

If you haven’t subscribed yet to the Cincom Smalltalk Resolutions Newsletter and are an active customer or partner, you can subscribe with your customer number here:

The refinements mentioned above are one example of how we listen to our customers and partners. Listening and responding are two important factors in providing a great customer and partner experience. Those conversations are valuable, not just to Cincom and Cincom Smalltalk, but also to our customers and partners, because it lets you have a voice and be heard. Conversations are not one-sided. It’s a continual dialog between our team and you, as we build a relationship that helps us see the unique perspective found in your requests. This provides a better understanding of your needs and likewise our product and communication direction.

Conversations with customers and partners help to guide our product direction and improve aspects of our messaging to better serve our customers and partners. For example, some have requested things like OAuth authentication and Opentalk STST improvements, and we have delivered those in the product. Recently, several customers requested a new and improved date widget in the product. As a result, the DatePicker was created, and product management supplied instructions on where to find it and multiple ways to integrate it into their applications through a series of Hidden Gems screencasts which we listed here in the March edition of the Cincom Smalltalk Digest

We’re always here to listen, learn from you and support your needs where possible. Do you have any feedback for our team? What are we doing right? What are we doing wrong? What could we do better? Are there other ways we can share information with you? Where do you get your information from? Perhaps there are websites, forums or social-media sites that we currently don’t subscribe to that you could share with us.

We value your input and want to make sure you know how to get in touch with us. Please send your comments or suggestions to the Cincom Smalltalk Product Team at


In this section, beginners to Smalltalk, freelancers and developers will read informative articles and see specific Smalltalk examples to help users learn new skills or enhance existing skills using Cincom Smalltalk.

What Is the REV 9.1 Program?

We mentioned earlier that Cincom Smalltalk 9.1 is now available for customers and partners. For those who are not a customer or partner but want to experience all the upgrades the new release offers, we have an option available for you … the Cincom Smalltalk REV 9.1 Program!

The REV 9.1 Program is a bridge between the Personal Use License and full licensing. It allows for an affordable entry into the Cincom platform, providing both the full product (the current release of Cincom Smalltalk Version 9.1) and full support for a one-year/12-month time period. REV 9.1 Program participants also have access to Cincom marketing and branding through the Cincom Smalltalk Partner Promotion Program that can help with the kickoff of their application or business.

Here’s how you begin:

  1. Step One:
    Listen as Suzanne discusses the REV Program and the benefits a user receives by becoming a partner with Cincom here.
  2. Step Two:
    Contact our product team for purchasing options and a passcode, as there are some restrictions. Check to see if the product is available to you by emailing the Cincom Smalltalk Product Team.

If you are not ready to make this modest investment for the REV 9.1 Program, but are still interested in trying out Cincom Smalltalk, the Personal Use License (PUL) is just for you. Cincom Smalltalk 9.1 is not currently available for the PUL, and the availability date has not been determined. However, the PUL is ideal for developers who are looking to sharpen their skills through a new developer tool.

With Cincom being a leading provider of commercial Smalltalk, the PUL also presents an opportunity for existing Smalltalkers to build their businesses and partner with a global commercial company. Regardless of the reason, the PUL allows the freedom for users to evaluate our products before realizing that Cincom Smalltalk is the right fit for their business or project needs. 

How do you begin this process?

Starting from Scratch: How Do You Communicate in Object-Oriented Programming?

In the following article, Jeremy Jordan, the Marketing Manager for Cincom Smalltalk, shares more about his first experience with object-oriented programming:

“Recently, I had an opportunity to try my hand at programming in Smalltalk. I’ve never programmed in my life, so this opportunity was both exciting and intimidating. Thankfully, one of our Cincom Smalltalk engineers recommended that I read the ‘Smalltalk User Guide’ found in Cincom ObjectStudio, which was a game-changer for me. After reading through some of this document, I finally understood what object-oriented programming represented, at least from a high level. Although this may be second nature to seasoned Smalltalkers, I would like to share another segment of snippets that I learned.”

The topics that follow provide a brief overview of the object-oriented principles that underlie Smalltalk programming. This section is all about communication, as we learn the definition of an object and how objects communicate. You will see that objects are used to model real-world entities, and that they have behavior and responsibilities.


An object is a combination of:

  • Some data elements
  • Operations that manipulate the data and/or perform other actions

Data elements
In other contexts, these data elements are called “fields” or “attributes.” In Smalltalk, the data elements are called “instance variables.” There are also other kinds of variables such as class variables, global variables and temporary variables. 

Operations that manipulate the data and/or perform other actions are the interface or behavior of the object. In Smalltalk, each individual procedure is called a method.


An object’s data elements are private to the object, and you cannot access them directly from outside the object. Instead, you must send a message to the object, asking for information. It is as if there is a wall between you and the data—you cannot see the data directly, but can only gain information by talking to the object and getting a response. For example, to determine the height of the man, you cannot just look at him (or read his mind); you must ask him: “What is your height?” 

This is called sending a message to the man. In Smalltalk, all programs are written by sending messages to objects. If the object understands the message, it will perform one of its methods and respond with an answer. If the object does not understand the message, it will tell you so. In Smalltalk, you write the pictured message as:

aMan whatIsYourHeight

aMan is the object and whatIsYourHeight is the message.

Notice that the message, whatIsYourHeight, is passed to the object, aMan. In more traditional languages, you pass data to functions.


The only access to an object’s data elements is through messages. This is a very important object-oriented principle called “encapsulation.” Encapsulation is useful because it decouples the behavior of the object from its internal implementation.

In the preceding object example, you do not care how the man calculates his height. He may know his height immediately. Or, he may have to measure himself each time. Or, he may have to ask his mother. The point of encapsulation is that you should not need to find out which method he uses.

Here are some other examples:

  • DatabaseTable object would have insert, update and delete messages as its interface, but the internal representation could be anything we want—a tree, a flat file, a hash table and so on.
  • A Float object. Do you know or care what the internal implementation of a float is? Or the implementation difference between an 8-byte float and a 4-byte float? Probably not. All you care about is the behavior of the float, not its implementation.

This separation of the interface from implementation greatly improves the reusability and maintainability of the design. Indeed, the encapsulation principle is also stressed strongly in structured programming. 

With object-oriented programming, users are learning a programming language and a new way of thinking. When learning a new language of any kind, says, “You need to experience a language through lots of exposure before you can hope to learn it.”  The same is true for object-oriented programming. The best way to learn OOP is to learn by immersing yourself in an environment, like Smalltalk, where you use objects all of the time.

How Can You Organize Your Applications with Tabs?

Arden Thomas, the Cincom Smalltalk Product Manager, started the Hidden Gems screencast to give specific Smalltalk examples to other developers. Arden crafted this video series to share these examples, shortcuts, tips and techniques that might make it easier for other developers.

Would you like to place your applications in Cincom VisualWorks (or tools in ObjectStudio and VisualWorks) in tabs? Beginning with Cincom Smalltalk 9.1, we make tabs simple. In this month’s new Hidden Gems screencast, Arden gives the viewer a sneak-peek into using tabs in Cincom VisualWorks 9.1 .

In this screencast, you will learn:

  • What TabbedWindow is
  • Where to find it
  • Where to find documentation
  • How to use it
  • Where examples are located

This screencast is part of the Techniques Series, which shows various techniques of how to accomplish or solve different tasks such as automating image build to creating a custom parser.

If you have questions, comments, ideas for other Smalltalk examples or suggestions for future Hidden Gems, please send an email to the Cincom Smalltalk Product Team at
