Functions with Default Values for Parameters

Functions can have default values for their parameters, for example:

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); } }

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:

#include "motorLib.c"

You can suppress warnings about unused functions by including the line:

#pragma systemFile // eliminates warning for "unreferenced" functions

in the top of that file.
