I had something like this happen to me just the other day,
too. In my case, I had two functions and the second was being
called inside the first to provide a parameter for the first.
Both the functions were named correctly in their respective
files, and both resided in the coyote directory, which is
ALWAYS on my IDL path.
But every time I would run this program after starting up
IDL, it would barf on the same line. Said it couldn't find
that second embedded function! I don't think I had ever
seen this happen before in IDL.
In any case, I inserted a STRICTARR compile option into
that program module, and the problem went away. I wonder
if something changed in the way IDL resolves functions?
Cheers,
David
