Type: verb
Use:  Read a celestial position from a TV image using cursor;
      Print result on terminal and in log.

Output adverbs:
  TVBUT.......Value of button(s) pushed: 1, 2, 4, or 8 are likely
              but combinations may be possible.
  COORDINA....The X and Y coordinates are found as:
              Xpos = abs(CO(1)) + abs(CO(2))/60 + abs(CO(3))/3600
                 if any of CO(1), CO(2), CO(3) < 0: Xpos = -Xpos
              Ypos = abs(CO(4)) + abs(CO(5))/60 + abs(CO(6))/3600
                 if any of CO(4), CO(5), CO(6) < 0: Ypos = -Ypos
              Note that, although these are most suited to RA, Dec in
              sexagesimal notation, they can be used for any type of
              coordinate.  The units are standard FITS units (e.g
              degrees, m/sec, Hz, sec, etc.) except that right
              ascensions are in hours of time.
