KEYWORD - Perform an EXTRAP interpolation over interior points.

INTEGER - Will gather points from cursor location at a radius given.

'INTERP performs an EXTRAP interpolation over all interior points.
See the EXTRAP subroutine document for more information.

Sets the minimum DN used in the interpolation formula.  The default is -9999.

Sets the maximum DN used in the interpolation formula.  The default is 32768.

Sets the interpolation radius to 1,000,000.  The default is 100,000.  See
the OPERATION section of this documentation for more information.

Specifies the percent of all points on the polygon border which will be used
in the interpolation formula.  The default is 100.

Read cursor position and display on the screen the picture and display
coordinates.

Position cursor at specified picture location.

Aquire vertices for specified circle radius from current cursor location.
At SARGON READY prompt or VERTEX ACQUISITION level move cursor to position
wanted and then type CIRC ##, where ## is an integer number.

Calculate Average DN, Standard Deviation, MINDN, and MAXDN for the specified
area.
