Back in the dim recesses of my memory I have a recollection that
findfile locates files by spawning a subprocess which performs an "ls"
which captures the output in a temporary file. The temporary file is
created in a directory defined by some environment variable TMPDIR,
TEMPDIR or the like, defaulting to /tmp. If this directory does not
exist, is not writeable (due to permissions, or quota or disk full etc)
then findfile fails.

Well, hard to say. But I did go through the Coyote Library
this morning to find and change all references to FindFile
to File_Search. All appears well now.
Thanks for the help.
Cheers,
