This will allow the user to display sections of a spectrum onto the terminal for examination. Unlike the AED it will. start at channel zero, and will print the actual numeric values.

‘Spectrum name?’ asks for the spectrum name that you wish to examine. The program, if it can find the spectrum, will respond with a line that will tell you how large the spectrum is.

‘Xstart, Xstop?’ asks you for the initial and final channel numbers to be printed. (If the input is reversed, it will assume that the largest of the two numbers to be the Xstop value, and the smallest value to be the Xstart value). The values will be set to the extreme of the spectrum if the channels requested do not exist. The program can display 7 channels (16 for byte spectra) or less at one time.

‘Ystart, Ystop?’ asks for the Ystart and Ystop values if the spectra is 2D. These are treated exactly the same as the Xstart and Xstop values.

Important; To leave this section of the program, an "Exit" or "Stop" must be typed when prompted for ‘Xstart,Xstop?’ or ‘Ystart,Ystop?’. A return is assumed to mean display channels 0 to 7 (0 to 16 for byte spectrum).
