I think you've misunderstood the CLtL2 description. That list only indicates
the kinds of things you can pass to the PATHNAME function without incurring a
type violation (which might signal an error, and might die horribly). The
string must still be syntactically valid; the error you are seeing is because
the string you've got there isn't valid. Some of the directory components are
seperated by ";" and others by ":". MCL2.0 uses ; separators in logical
pathnames (as per spec) and : separators when naming physical pathnames. You
can't mix the two.
