Find coordinates of a cell with maximum value in a floating point grid

Run this aml from the GRID prompt:

Code:
/* USAGE: &RUN XYOFMAX.AML <input_grid>
&args ingrd
&describe %ingrd%
z1 = scalar(%grd$zmin%)
docell
 if (%ingrd% > z1)
   begin
    z1 := %ingrd%
    xmap := scalar($$xmap)
    ymap := scalar($$ymap)
   end
end
&ty [show scalar xmap]
&ty [show scalar ymap]
&return

Note: This is not an ESRI supported aml. Use at your own risk. Please make a backup of your data before running this aml and carefully check the output. This aml does no error checking and it is meant only as a guide to developing an aml specific to your data inputs and desired outputs.

There is no provision within this methodology to identify multiple occurrences of the maximum value.
