    Do you ever wonder how many licenses are really being used? Are engineers saying they don’t have any licenses available when they need them? We have added Floating License Tracking to make answering these questions a little easier. After upgrading the License Manager to build 793 or later, the server administrator can choose a location to save the log file, and start logging right from the License Manager GUI.


    Once the logging is enabled take a look at the different graphs that are available by selecting the ‘Reporting’ tab. If your license file consists of different major versions of Understand, they will be color coded and divided up accordingly.


    License Usage by Month



    License Usage by Week



    License Usage Daily

    Notice that these graphs also show the number of times that a license was denied, meaning that all of the licenses were already in use when an engineer tried to get a license. This can help a team know if they need more licenses and help determine how many are needed.


    If you like to see the raw data, or just want to see some more details, take a look at the log table that is available under the Reporting->Log Table tab. If you still want more data than this, let us know and we can give you details about how to get even more with a little custom work.

    Great news, if your team uses floating licenses you now have the option to checkout a license when you travel!

    When this feature is enabled by your server administrator a new section will appear in the Help->Licensing dialog in Understand while you are connected to the license server:

    ToGo Client

    Simply select the number of days you want to keep the license and hit the “Checkout” button. At that point you can disconnect from the network and you will have an Understand license on your machine until the time expires or, if you get back to the office early, you can hit the “Checkin” button.

    togo checkin


    This feature, which we are calling “ToGo” is disabled by default and needs to first be enabled on the floating license server with the Instructions below; you will also need Understand 4.0 build 790 or later.

    License Manager Setup

    1. First, make sure the license manager is running build 790 or later. You can get the license build from

    2. Next look for the ToGo line in your license.dat file and change the number from 0 to the maximum number of days you want users to be able to keep a license. If the line doesn’t exist you can type it in manually before the “Server:” Line

    togo license file

    3. Start and stop the license server and it should be all done, Enjoy!

    When using Understand it is possible to get to a point when you have quite a few windows open and want to be able to “browse” through the windows quicker and easier. The Window Selector is the perfect choice for this.

    To open the Window Selector, choose ‘View->Window Selector. Notice that it shows several graphs and a number of source files in the list. I can easily click on any of these or use my keyboard to access them, and quickly see the file or graph that I am interested in.


    Notice that the list does not show me the Entity Filter, Information Browser, or any of the Understand windows that I may also want to choose from. To change that, simply click on the Show: drop down arrow and select the option that best suits your needs. For me, I like to see ‘All Windows’, which then gives me the view shown below on the right.


    There are also options available to be specific about how the items are sorted, how short or long the Filename is, and even a ‘Filter’ field at the bottom of the window.

    Hopefully the Window Selector will make browsing your open windows and documents a little easier.


    On a side note…there is a simplified version of the Window Selector that can be accessed quickly with the keyboard shortcut ‘Ctrl+Tab’. This temporarily opens a separate window that acts the same as the Window Selector but without all the options. The window closes when a file is selected.

    If you find yourself frequently adding boilerplate text, changing the same kind of text, or repeating something over and over again in the editor, macros may be your new best friend. You can record your actions in the editor, and then save them and replay them at whatever location you want. This is much more than copy and paste, you can record arrow key movements, keyboard shortcuts, deleting, actual typed text, and much more. Then you can add keyboard shortcuts to each of those recorded macros. Give it a shot!

    Your code has tons of important relationships in it and we want to help you find find them. With Understand 4.0 we’ve added several new graphs that let you track the relationship between two specified entities. For example if are only interested in how two functions interact with each other in a call or callby tree you can now see it. Right click on the first entity and select “Graphical Views->Calls Relationship” or Called-By Relationship. You will then be prompted to specify the second entity by clicking on that entity name in any open Understand window. The final graph shows only the call trees between those two entities.

    Here is the call tree graph for the function _docall. If I am only interested in the relationship between _docall and the highlighted function “fatal” there is a lot of extra information in my way.




    With the new graph I can get the desired information in a much more condensed manner:



    There are also options to highlight, aggregate and hide nodes. For instance I can aggregate the functions by file for an even more informative view:

    CallsRelationshipGraph-_docall-fatal -file


    These new relationship graphs are available for calls, includes, overrides and base/derive relationships. What entities will you explore with this?

    Build 771 adds the new UML Sequence Diagram graph.

    A Sequence Diagram is an interaction diagram that shows how processes operate with one another and what is their order. A sequence diagram shows object interactions arranged in time sequence. It depicts the objects and classes involved in the scenario and the sequence of messages exchanged between the objects needed to carry out the functionality of the scenario.

    A sequence diagram shows, as parallel vertical lines (lifelines), different processes or objects that live simultaneously, and, as horizontal arrows, the messages exchanged between them, in the order in which they occur. This allows the specification of simple runtime scenarios in a graphical manner.


    In Understand this graph is available for functions and methods that call member methods.

    A new version of the control flow graph has been added that allows much more interactivity. You can access this graph by right clicking on a function or method and selecting Graphical Views->Cluster Control Flow. The new graph lets you collapse and expand subsections of the graph by double clicking in the bounding box of that area. You can also hide parts of the graph that you are not interested in.

    Here is the same function with the cluster control flow graph on the right, and the regular control flow on the left.

    control flow graphs


    Note how parts of the graph are clustered together, double clicking in that area collapses it:



    This extra interactivity gives you the ability to work with much larger graphs while still only focusing on the areas that are important to you

    Understand now has a selection of predefined themes that let you quickly change the look and feel of the editor. These themes can be accessed under Tools->Options->Editor->Styles. The Predefined: section at the top of the page lets you select the theme you want, and you can customize the theme to your liking.

    predefined theme

    Here are what several of the themes look like:

    Understand Theme

    Understand Theme

    Terminal Theme

    Terminal Theme

    Silver Theme

    Silver Theme

    Onyx Theme

    Onyx Theme

    Classic Theme

    Classic Theme

    Aqua Theme

    Aqua Theme




    If you like most of a predefined theme but want to “tweak” a few items, make sure to take a look at the options available for each supported language.





    For Application Styles, go to Tools->Options->User Interface->Application Styles and select your custom options there. Note that the ‘Use Editor Colors’ button is very useful for quickly matching the Editor Styles to the Application Styles.



    Happy Coding and Color Customizing!
