I have written and continuously use many functions that take filenames
as argument, without any problems. I recommend you carefully check the
syntax you are calling the function with. One very formal way of
insuring correct syntax of filenames (at least this works on the Mac,
DOS-based filenaming is a bit of a problem for Mma and I haven't worked
in that environment as much. I believe it works there, too, though ...)
is to generate a list of filenames I want to manipulate using
and then use an index into nL as argument to myfunction[].
