SELF TEST
Determine the output of the following program

	program WHILE_DEMO (output);
	const   PI = 3.14;
	var     XL, Frequency, Inductance : real
	begin
	        Inductance := 1.0;
	        Frequency  := 100.00;
	        while  Frequency < 1000.00 do
	        begin
	            XL := 2 * PI * Frequency * Inductance;
	            writeln('XL at ',Frequency:4:0,' hertz = ', XL:8:2 );
	            Frequency := Frequency + 100.00
	        end
	 end.


	Self test .. Output of program WHILE_DEMO is..
	XL at  100 hertz = ..........
	XL at  200 hertz = ..........
	.............................
	XL at 1000 hertz = ..........
