Hi there, I know this is a very easy task to do, but for some reason I
can't get it to work. I have a .img file into the IDL code folder
(where I save all the source code), then I run the following lines:

openr, 1, filepath('filename.img')
image = fltarr(xsize, ysize, zsize)
readu, 1, image
close, 1

but I keep getting error message that the system cannot find the file
specified.
I thought as long as the .img file is located in the source code
folder, i don't need to list the full address. What did I do wrong?
