Changing values of one image from ENVI [message #62270]

Hello,
I would like to change some pixel values of one image loaded with
ENVI_OPEN_FILE, but I cannot load the entire image in memory (this is
a very big image).
What I do is to access and process some specific regions of the image
using ENVI_GET_DATA, by defining subsets in DIMS.
I really wonder if there is any keyword in the procedure
ENVI_WRITE_ENVI_FILE, or other procedure (something inverse to
ENVI_GET_DATA) to perform this, because the only choice that I know is
to load the whole image in memory in IDL and write it again.

Thanks

Txomin
