Program Comments
10: Program file name.
20 Sets the number of points in the waveform.
30: Defines arrays for I and Q waveform points. Sets them to be integer arrays.
40: Sets HP BASIC to use degrees for cosine and sine functions.
50: Sets up loop to calculate waveform points.
60: Calculates I waveform points.
70: Calculates Q waveform points.
