Flowcode can simulate C code inside C Code icons. Note, in order to use this feature you will need to have purchased the Professional or Academic license.

	This feature can be great for debugging custom C code within your project, prior to compilation to a microcontroller. It is also invaluable as a teaching tool, and allows you to teach students the effects of certain C language statements on variables. When simulating C code, you can step through individual statements within a block in the same way that you step through multiple icons in your Flowchart.

	However, the behaviour of these variable types cannot be guaranteed to be the same between various compiler families. Therefore, we recommend that you use the Flowcode types from the above table in order to keep your code as portable ~~as possible between different microcontrollers~~.		However, the behaviour of these variable types cannot be guaranteed to be the same between various compiler families. Therefore, if you plan on compiling your code to a microcontroller, we recommend that you use the Flowcode types from the above table in order to keep your code as portable. On the other hand, the native C data types can be useful for educational purposes.

			===User-defined macros===

	Flowcode is also able to simulate the effects of calling your own user-defined macros. In C code, user-macros are referred to using the prefix "FCM_". For example, if we defined a user-macro called "Func", which returned a byte, and required an integer as a parameter, then we could write the following C code, which would successfully simulate.
