Easy to understand output
The classic method to interact with the computer is to
use the "Console". Using this approach, the program displays output
on a text-only screen and the user
inputs data using the keyboard. Sometimes the console allows the
text to change colors, but, for the most part, it is white text on a
The Console works, but its simple interface can make it difficult
to differentiate user input and program output. So, rather than using the text-only screen,
Flowgorithm attempts to make it look like a typical instant
messenger window. From the programmers point of view, it looks like
they are texting with the computer.
The "chat bubbles" are color coded to match the Input and Output
shapes used in the flowchart. In the screenshot to the right, the
user's input is display in blue while the program's output is
displayed in green.
If you don't want to use the chat bubbles, you can also toggle
between them and the classical plain text.

Graphical variable watch window
The variable watch window is used to keep track of how your
variables are changing as your program executes. So, if you are
stepping through your program, the window will show each variable
and its current value. This is not limited to just basic variables.
Arrays will be displayed as well.
Each variable is color coded based on its
data type. At a glace, you can tell exactly what type of data is being
stored - and catch where you may want to use a different data type.
- Integers are displayed in blue.
- Real numbers (doubles) are displayed in purple.
- String variables are a displayed in red.
- Boolean variables are displayed in teal.
3 introduced turtle graphis into Flowgorithm. The idea comes from the
classic programming language LOGO which was developed in 1967. It allows
images to be created by the simple actions of the "turtle" - a graphical
"brush" what be be turned and moved to create images. The goal was to teach
programming concepts through the sequental steps required to create an
- Turn - changes the angle by rotating the Turtle either left or
- Forward - moves the Turtle the specified distance.
- Home - returns the turtle to the start position and sets the angle
at 90 degress.
The introduction of turtle graphics will give instructors one additional
tool to teach programming. For example, instructors could ask the studenst
to draw a rectangle - first through a sequence of steps, then later, using
Basic File Support
Version 3 added support for basic file input/output. Using the new four
shapes, Flowgorithm and read or write simple text to a file. Students will
be able to generate output files, or open input files can perform
calculations on a large data set.
The shapes for Read and Write were previously defined in flowcharts.
However, the Open and Close shapes are original (but designed to be visually
Customizable Color Schemes
Flowgorithm supports a wide-variable of color schemes. These will
allow you to work, or export the flowchart to an image file, in a
number of different styles and appearances. The application comes
with a selection of built-in schemes.
You can also
download over 100 additional schemes from
this website. The application, itself, can download them automatically.
If you want an appearance that is not currently supported,
Flowgorithm has a Color Scheme Editor where you can
create your own.
With Version 3, colors can also be applied ot the entire applciation. So,
Flowgorithm can have a dark theme, light theme, or
any color - for that matter. The picture below shows Cyberspace color theme
applied to all windows..
3 introduced Conditional Breaks. In the previous version of Flowgorithm,
breaks would always halt program execution (the user could continue). Now,
the Breapoint Shape either can use this behavior (the default) or only break if a conditional expression is
true. This should make the break shape a tad more useful - especially for

The Source Code Viewer can convert your flowchart to several major programming languages.
If you planning to learn a high-level language, then this

is highlighted using the same color used by the flowchart's matching
shapes. This allows you see visually see the correlation between the
code and flowchart. Also, if
you highlight shapes in the flowchart, or you step through your
program, the source code will be highlighted to match.
The following programming languages are supported:
- Ada 95
- Fortran 2003
- VBA (Visual Basic for Applications)
- Visual Basic .NET
The following pseudocode are also supported:
- Auto Pseudocode - created using the current translation
such as Spanish, Arabic, Korean, Italian, etc...
- Gaddis Pseudocode - used in the book "Programming Logic
and Design" by Tony Gaddis.
- IBO Pseudocode
your programming language and/or pseudocode is not listed,
Flowgorithm supports customizable program templates. These are
simple text files that can be written with any text editor. Once
loaded, your flowchart can be automatically converted to the target
syntax. Please check out the online
supports multiple spoken languages. If your language isn't currently
supported, and you would like to help create a translation, please
contact me at: FlowgorithmDevinCook.com. No
programming is required. You just need to translate a simple text file..
Your help will be greatly appreciated!!
- Chinese (Simplified)
- Chinese (Traditional)
- English - U.S. & British
- Spanish - Mexican & Castilian
- Single dimensional arrays
- Pre-test and Post-test loops
- For loops
- Explicit variable declaration.
Flowcharts generally use implicit declaration (given they are
quite minimalistic). However, practically all languages use
explicit declarations. So, it's a good idea for students to
learn it from the start.
- Safe recursion. Flowgorithm maintains an internal stack
(rather than the system stack). If the student accidentally
creates an runaway recursive call, the program will not crash.
Instead, they will receive an error message.
- Supports operators
from multiple syntaxes that are used in programming languages.
This includes the C family, BASIC family, and the mathematical
symbols themselves (Unicode).
You can use any of operators - depending on the
high-level language you want to learn later.
- User-defined functions are supported. These include ones that return a
value or nothing at all.
- Over 20 intrinsic functions.
- Several flowcharting styles are supported. This includes:
classic, IBM, SDL, and more...
Flowcharts can be exported to both PNG (bitmap) and SVG (vector)
in any of the color schemes.
- The Editor has a feature called "Layout Windows". It is designed
to help instructors show the all the needed content on the
screen without having to manually resize each window (which can
- Programs are saved using XML.
