	Take, for example, the problem of a program which accepts
a file specification as one of its parameters.  The file specification
does not necessarally have to include the current directory.  If
so, using DOS's find-first/next routines will determine if file
exists, but does not give a true file name.

	In Turbo Pascal, the FSplit takes as an argument a file
path and will return the three components of this path:  the
directory, file name, and file extension.  Does such a routine
exist in MSC?  The run-time library routines do not appear to have
such a routine.  What about a built-in DOS function?  Again, I have
checked several sources of documentation, and none appeared to have
such a routine listed.  I'm sure I could easily scan the path string
for the arguments I need and build my own routine, but I would
prefer to use any existing routines, in order to keep my code size
down to a minimum.
