A few years ago I was trying to setup ways to get pretty precise timing for MIDI signals coming out of Lemur. It involved setting up loops based on having globals that I could use inside of a procedure which could then be used across several procs. Hence my dismay over the original forum disappearing. Along with that forum went a couple of years of notes and code postings, (AaAAAAAAAAAAAAAaaaaaaaaaaaa.............) So now not having a photographic mind I need to refresh how the timing works. So if anyone out there can give me a quick overview of Lemur frames I'd really appreciate it.
With that in mind I'm also wondering why I'm getting multiple MIDI records for what I believe is just a single call to noteout. Gotta run, to be continued

I have the following code in a button:
decl z,w;
z = time +10;
AAmsg = z;
while(time<z){w=1;}
AAmsg = 'done';
I have 2 monitor objects in 1 is the variable time which ticks away nicely.
In the other I have AAmsg which first shows me z.
Then I watch the time field go right past the z field and it never changes to 'done'
Now we know why I miss the other forum. Thank you very little liine!!!!
maccazia where are you when I need you!

You've created a 'trap' with the while(time<z){w=1;} statement. The code execution gets stuck there so nothing updates.
Here are some steps I followed to achieve what I think you're trying to do:
-----------------------------------------------------------------------------------
1. Add a CustomButton to the canvas, call it Btn.
2. Add two variables to it call AAmsg and var (which is your 'z', but I stay away from using 'z' because it's sometimes an internal variable like 'x'). You should now have three variables: x, AAmsg, and var.
3. Add two scripts: reset() and UpdateAAmsg()
4. reset() will be:
Execution: On Expression, x, rising.
var=time+10;
5. UpdateAAmsg() will be:
Execution: On Frame
if(time<var) AAmsg = 'Waiting...';
else AAmsg = 'done';
6. Add a Monitor to the canvas and set its value to Btn.AAmsg
-----------------------------------------------------------------------------------
