The TEREADYWHEN with Strictrecognition provides a tight
transition environment--you code it prior to the transition,
then check screen.readyID to see which screen came-up.
Then, the global.screentimeout section (<tesection
screentimeout> inside of global.stml) can be added to
global.stml to add an event-driven block of script that will
execute any time a screen transition fails, with or without
a TEREADYWHEN, but anywhere there is a TEREADYWHEN with
strictrecognition, if a screen appears that is unknown, it
will fire the screentimeout section.
