CURVALUE
Type:  Verb
Use:   To perform an interactive display of the pixel locations and
       values of those images visible on the TV.  The X and Y pixel
       coordinates, the pixel value, and the units of the pixel value
       are displayed in TV graphics channels 2 and 8 at the upper left
       hand corner of the display.  The cursor position determines which
       pixel is shown.  Button D causes the verb to exit.  The pixel
       values are read from disk, if possible, to preserve accuracy and
       dynamic range.  When the images were loaded by another computer
       or were temporary images (e.g., IMAGR residuals), the pixel
       values are read from the TV and suffer from limited accuracy and
       clipping
Adverbs: none
