You could also use one of two options if you want to stick to using
ENVI displays:

If you want to have a routine that just gets the current coordinates
under the cursor, then operate on those coordinates only, then you
should probably use DISP_GET_LOCATION.

If you want a routine that continuously updates as the cursor is moved
around in the image display, then you will probably want to set up a
"user defined move" or "user defined motion" routine (i always forget
the difference between the two). See ENVI documentation for those,
they require a preference setting to work.
