-- This code should do the trick.  Remember to do a #define INCL_DOSFILEMGR
to get the right include files included.  The first parameter is the file spec
so you can use , for example "c:\\*.*", etc, here.  For the file options, 
you have to decide what you want.  This system call is capable of reading 
hiddens, etc, so you might normally use FILE_NORMAL  ie files that "dir" 
can find.

Remember, this does not return the oldest file.  You cannot get this 
information, as if a deleted file is written over, its place may be used
by a new file.  

Incidentally, this code is virtually identical to the MS-DOS int 21/4eh
system call.
