The BS2 is a single-tasking processor.
It doesn't do 'Events'.

In VB, you are in a windowing environment, where
'events' are passed around to windows, so the
code for that window can respond and update the
window. It's inherently multi-tasking. You
have multiple windows, with one or more
window event-handler apps behind them.

The BS2 comes from an earlier processing model,
that of the single execution stream. Now, you
CAN implement a 'state machine' in PBasic, and
cycle the 'state machine' fast enough so all
'pseudotasks' get some time.

Like:
MyState = 1
StateMachine:
BRANCH MyState, (IdleTask, Task1, Task2, Task3)

IdleTask:
' Wait for time tick
GOTO StateMachine

Task1:
' Do task 1
GOTO StateMachine
'etc.
