Hi Sylvain,

Actually, the 'do' command _is_ executed, but it
doesn't cause myHandler to exit.
Look at it this way: when you execute a 'do' command,
the statements in the do are wrapped as a sub-routine.
Sub-routines cannot exit the routines that call them.
You _can_ do it if you change the statement to:
  do "exit to top"
but that will end all the handlers in the call chain.

Hope this cleared things up a bit,

Jan Schenkel.
