yes it would be faster, if you could really see the speed because it
has only one variable to display, i
You do not need the line TestArray = C; at all.

In fact ifthat is all you wanted why not just use this, as you do not
need loop at all

printf( "The Value of TestArray[" + NumToStr(barindex(),1) + "] is " + "38.21");
