		+	Functions can have default values for their parameters, for example:<br />
		+	{\|
		+	\|-
		+	\|<syntaxhighlight lang="ROBOTC">
		+	void forward( int speed = 100 )
		+	{
		+	motor[ port2 ] = speed;
		+	}
		+
		+	task main()
		+	{
		+	// Forward at default
		+	forward( );
		+
		+	// Forward at speed 10
		+	forward( 10 );
		+
		+	// Do nothing
		+	while( true ){
		+	wait10Msec(500);
		+	}
		+	}
		+	</syntaxhighlight>
		+	\|}<br />
		+	If the function "forward" is called with no parameters then the default of 100 is used.
		+
		+
		+	If you have included your own library of functions, for example:<br />
		+	{\|
		+	\|-
		+	\|<syntaxhighlight lang="ROBOTC">
		+	#include "motorLib.c"
		+	</syntaxhighlight>
		+	\|}<br />
		+
		+	You can suppress warnings about unused functions by including the line:<br />
		+	{\|
		+	\|-
		+	\|<syntaxhighlight lang="ROBOTC">
		+	#pragma systemFile // eliminates warning for "unreferenced" functions
		+	</syntaxhighlight>
		+	\|}<br />
