RE: [Tcl-nap-users] return NAO object

Hi Salah,

          This can be a bit tricky the bottom line is to make the last
thing in the procedure the result and do not assign it to anything.

If you are using the procedure as a nap function then you can use return
to return the result.

=20

        proc st {}  {

            nap "{1 2 3 4}"

        }

=20

         nap img =3D [st]

=20

        will work

=20

        nap img =3D st()

=20

        will not work because the function must have at least 1 argument

=20

        proc st1 {a} {

=20

               nap "{1 2 3 4}"

         }

=20

=20

         nap img =3D st1(3)

=20

         or=20

      =20

         nap img =3D [st1 3]

=20

         will work.

   When using procedures as nap functions the function parameters are
separated by , and must be NAOs. The result should also be a nao.
Procedures can return a NAO, however,  you need to do something like the
first example to return a result. If the result was in a NAO called say
"a" then put "nap a" as the last statement in the procedure.
