Thanks.
I have been trying this without much luck, the "tcl name" (which above is
Application/MyApp) is just a text string, righ? so as long as the string
matches between the parameter to the TclClass statement, mactches with the
Tcl set statement it should work?(In my case it doesn't). I still get the
same error message:

invalid command name "App"
    while executing
"App create _o34 "
    invoked from within
"catch "$className create $o $args" msg"
    (procedure "new" line 3)
    invoked from within
"new App"
    (file "Apptest.tcl" line 27)
