TRACE question

[Jeffrey Grossman <Grossman@YALE.ARPA>]

  If I trace procedure FOO and then call it, T provides me with information about
FOO's arguments and return value.  However, if I APPLY FOO to its arguments, then
TRACE tells me nothing.

  1 Why is this so?
  2 Can T be made to give similar information when APPLY-ing a procedure?
