// First we declare any functions and variables that we're going to use
// They can be declared anywhere in the script
// as long as they're declared before we use them
// Note we don't need to declare the 'built-in' system functions like HubInit()
Func1();
Func2(float val);

string sMessage;

// The first function is usually HubInit()
// This is always called when FreeWay powers up
HubInit()
{
  // print a welcome message to the debug Telnet interface
  DebugPrint("Welcome to the FreeWay demo script! \n\r");
}

// Now we'll define a function that we'll call from the FreeWay's
// built-in Web Page
Func1()
{
  // Print out a debug message
  DebugPrint("Func1 has been called \n\r");
}

// This function demonstrates how to pass a numeric value to the function
// the value is converted into text and printed out
Func2(float val)
{
  // build the message 
  sMessage = "You passed value " + format(val,1,0) + " to Func2 \n\r"; 
  // print out the message
  DebugPrint(sMessage);
}
