It is difficult to give precise answers when you state neither the
platform (hardware and OS), nor the compiler you are using.

The most portable approach I can suggest is to use the appropriate one
of the existing Ada bindings for POSIX 1003.5

For Win32 there is a partial binding that includes what you need at:
http://perso.wanadoo.fr/pascal.obry/w32posix.html

For UNIX platforms, you can look for the FLORIST bindings in several
places.  The generic implementation is at
ftp://ftp.cs.fsu.edu/pub/PART/FLORIST/
there are also implementations at
ftp://ftp.cs.nyu.edu/pub/gnat/florist/ and at
http://www.gnuada.org/alt.html

Once you have the proper POSIX library for your platform and compiler,
use the subprograms in the package POSIX.Files

Reading Filenames

[-=[CheecH]=-]

I want to write a little programme which can read in all the filenames in a
directory and write them to a text file.  But I have have no idea how to
read all the names in.  Can any one help please.

If you use GNAT look for the file g-dirope.ads in your adainclude directory:

<<
--  This package provides routines for manipulating directories. A directory
--  can be treated as a file, using open and close routines, and a scanning
--  routine is provided for iterating through the entries in a directory.

package GNAT.Directory_Operations is
