Documentation is always the last thing to get done....
Until I get it completed, your best bet is to read the lego
documentation - especially the opcodes monel,monex,monal, and monax.
The monitor/catch works like this:
monitor(events)
{
// body
}
catch
{
// handler
}
monel events, handler
body code
monex
goto done
handler:
handler code
done:
Essentially, the monitor command begins even monitoring (within the
body) and if an event occurs, the handler is invoked. the acquire/catch
construct is similar but uses monal/monax instead of the event stuff.
I haven't played much with resource acquisition. Event handling is
pretty cool though. You'll first need to setup the events. Use
SetEvent() to setup a specific event source. You can also use Set() to
tweak things like the hi/low thresholds....for example:
Set(LowerLimit(0), 10); // set lower threshold for event 0 to 10
I'll try to post an example or two after the next release (mostly
because the SetEvent() call is going to change a bit to make things a
bit easier).
