It is simply the interactive (second) half if the verb TVALL. If button A is hit, the routine allows alteration of the black and white transfer function (cursor X sets intercept and Y sets slope). If A is hit again, the color contour enhancement is performed (cursor X sets starting point of contours, Y sets width). If button B is hit, the zoom magnification is incremented and the cursor position controls the position about which the image is zoomed. Button C is like Button B except the magnification is decremented. Hit button D to exit. Adverbs: TVCHAN......Specifies which channel is to be "fiddled". The channel must be one of the channels currently turned on. TVLEVS......Specifies the maximum intensity expected for the sum of all visible, overlapped images. Usually n x max in one image which is now 2046. Values < 2046 are made 2046. ----------------------------------------------------------------
