Hi Jean;
Thanks a lot for the advice. It did the trick! I used
envi_write_envi_file to write a file to memory and then
envi_output_to_external_format to retrieve that file and write it to
to an ASCII file. In the call I used the new file's id and added the
"dims" and "pos" keywords which I had forgotten to include too. I just
have to resize the arrays and do a couple of more things to get it all
right, but I am on my way now.

Lorenzo.
