tcc /c {cmd} - how to get the value of cmd in TCEXIT

i would like to tweak my TCEXIT.BTM so that it checks the exist code (done) and if we had a problem, does a PAUSE (so that I have a chance to see what was going in a cmd session that whatever link may have fired).

Now, is it possible when a session was started with /c {myCmd} to execute a command find out what that command was?
