This could well be a bit of a long shot...but I noticed that the output
filename was not defined properly in the code you gave. You had the code:

oname=/temp.img'

As far as I can see there may be two things wrong with that:

1) It needs a ' at the beginning to make it a valid string (although the
compiler will probably catch that, so I guess that's a typo when copying
to the newsgroup

2) A filename of "/temp.img" on a Linux/Unix/OS X machine may well not
be able to be written to, as you are unlikely to have write access to
the root of the root filesystem.

ENVI_FILE_OPEN will give an rfid of -1 if it couldn't open the file, so
if the file hadn't been written properly in the first place then that
might explain why.

It's just a crazy idea...but it can often be the simplest things that
cause the major problems (I know I've done this before).

Cheers,

Robin
