ENVI: procedure to get X, Y of pixel in displayed image [message #52089]

Hi,
i'm getting troubled with writing a procedure to get x,y (so: y = the
line of the image (row) and x = the sample (column)) coordinates of a
pixel of a displayed image. I'm trying to do this with cursor, but
while debugging I don't have the results I want.

I'm using

cursor, x, y, 4, /DATA

I saw that with
cursor, x, y, 4, /DEVICE
I get integers instead of floats.

I would to like what I'm doing wrong.
Also, I would to know if somebody have written a procedure to get
coordinates and value of a pixel by clicking on it on the display.

Thank you.
