1. profile_time in win32 euphoria
Is there any way to get profile_time in win32 euphoria to be added,
that would be real cool.

I'd like to have that too.
I just need someone to show me how to get
a timer interrupt generated, say, 100 times per second,
and then the rest of it should be just like
what I do for DOS. I know it can be done. I just never
persued it long and hard enough.

Wouldn't a win32 timer be appropriate?

Obviously, not a lot of searching.... I found it in a couple minutes
(though I /did/ know what to look for already.) Your best bet would be the
SetTimer function (
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winui/winui/windowsuserinterface/windowing/timers/timerreference/timerfunctions/settimer.asp
). The multimedia functions would be unstable for this kind of application
(they're very restricted), and the high-performance timers would just be a
waste. The performance monitoring API's Derek mentioned are NT/2K/XP only, I
believe, but too complex anyway, really.

Thanks.
I'm not sure SetTimer will do what I want, but I'll look into it.
I get the impression it's more of an application-level timer.
In DOS, I have a precise machine-level interrupt that I handle
at a low level, even to the point of looking at CPU registers.
SetTimer seems to just place a stream of messages into a queue,
and I'm not sure if it even does that preemptively or not.

Especially the secion on high resolution timers.

Thanks.
Using a high resolution timer would be a fairly easy
approach to time profiling. I could measure the total
time spent in each subroutine. Measuring individual statements
might be too fine-grained. Perhaps this would be easier than
trying to re-use my DOS profiling code. The DOS code works
by sampling the program's code address many times per second.

Well, I agree that to-the-statement profiling might be too
fine-grained, but it would certainly be useful to see time spent in
loop constructs (for, while) as well as the time for the entire
subroutine.

Plus the time the return statement takes when a lot of local vars are being
freed.
So, even if strict to-the-statement timing is overkill, blocks (as you said)
or specific statements may deserve it.

SetTimer has an option to call a function instead of posting messages to a
window. However, since you might be changing the code entirely, it would be
best to use the high-resolution timers. They are not always installed
though, so you may have to fall back to using SetTimer.
