There are still ways of referencing objects dynamically, just not as easily as in an interpreted language where tags are interpreted from the inside out.
I know I may be just dreaming here, but the current functionality of the TCF is already there and working, I would just like the added ability to compile it, and the compiler will make me have to apply some stricter methods of writing the code, but that is a small price to pay.
Do you know where I can find recent documentation on the new bean handler? I want to do some tests with beans, but there are many types and ways to write beans, and I want to conform to how Witango handles them. I have asked Witango, but have not heard back. They have no excuse, it is not there indepence. ;-)

Interesting,
As a matter of fact I use stored procedures in my database for a lot of the big looping of 10s of thousands of records. But that is not portable and doesn't solve the issue of looping speed within Witango.
I see now that dynamics within loops with compiler based languages have come a long way since I last tried.
I just don't want to loose the capability of dynamically creating object references.
There is a plus side, the continual speed increase on processors. When I run it on a Pentium 2 400Mhz server it takes a minute and a half :-)

I thought of that, so I made the instantiation a domain scope, then removed it for the subsequent times. I was surprised, it didn't not seem to have any effect. It must have only added a few milliseconds. Either way the TCF method was slightly slower or the same.
I agree that no one is going to look at that many years, but it was a good example to use as a comparison.
The reason I am so hot on this, is that I have several reports that I need to write, that require alot of looping and processing, and it just
chokes the witango server, and I need to right them in RB. I think if we had the choice quick and easy compiled code, then this would be less
of a problem.

I have tested your new TAFs. The TAFs that don't call the TCF method, both run 14 to 15 seconds consistently. The TAF that calls the TCF takes 15 to 16 seconds consistently.
Does anyone have any updated docs on developing beans for use in Witango?

Ok, so you are cleaning my clock :-)
I have changed the calcs into a TCF and also matched your logic.
Robert, Could you run the test against your server with the new "workdates3.taf" which calls "daycalc.tcf"?
This will be a more accurate time run because it is using the seconds
model you used in RB.
also included is the seconds logic in just a taf "workdates2.taf" (no
tcf call) could you run this time test on your server

OK, I created an application in RealBasic, and compiled for all platforms. It can be downloaded here:
http://public.bighead.net/workdaytest/
I also set up the workday taf on my test server and it can be run
here:
http://poh.bighead.net/workday/
With the default values, spanning 46020 days my witango v5.1.058
server
running on Windows 2000 server, AMD proc. running at 1.5ghz, with 512megs ram, and a 266FSB, it should take 15 seconds. If it takes longer, it is because a couple of you are hitting it at once.
Now If I run my RB app on the same machine, it takes about 1/3 of a second if I do not give a progress indication, and about a second if
mydo. That is even more of a performance increase than I expected. On
newmac, the results are about the same, except the progress calc takes just over 2 seconds.
Also, I am running my calc within its own thread. If I were to not thread the process, and disable background tasks, I could probably squeeze out another 10% performance.
Here is my code from the RB method, you can download the rb project from the link above:
Sub calcWDays() dim sDate,eDate,iDate as date dim nDays,wDays,sTicks,eTicks as double dim i as integer dim s as string
sTicks = ticks
sDate = new date eDate = new date
sDate.year = sDateDC.year sDate.month = sDateDC.month sDate.day = sDateDC.day
eDate.year = eDateDC.year eDate.month = eDateDC.month eDate.day = eDateDC.day
nDays = (eDate.totalSeconds - sDate.totalSeconds)/86400
wDays = 0 iDate = new date iDate = sDate for i = 1 to nDays s = str(iDate.DayOfWeek) if iDate.dayofweek > 1 and iDate.dayofweek < 7 then wDays = wDays + 1 end if iDate.TotalSeconds = iDate.TotalSeconds + 86400 next eTicks = ticks s = "The total number of dates between "+sDate.abbreviatedDate+" and "+eDate.abbreviatedDate+" is "+str(nDays)+". " s = s + "The number of workdays in between is "+str(wDays)+" and the time taken to calculate was "+str((eTicks-sTicks)/60)+" seconds." msgBox s
End Sub
I tried to make the RB method as Identical to the one in Ben's taf as possible as you can see. sDateDC and eDateDC are the date control objects that the user interacts with.

Actually, you could instantiate one field, then build an array of fields to the nth, building an array of field objects, and then loop through them referencing like so:
for x = 1 to 10000000 field(x) = "some value" next x
I just downloaded your weekday taf, I will do a test with it.

Yes, when all factors are know the compiled code is quick.
In your example you have 10 and it looks nice an simple. Now multiply it by 10 and then maintain it. :-P
Take the example I just sent with workdates.taf write a case statement for all possible dates. Aaaaaah.
The number of times that I had a loop that I know all the factors I could probably count on my hands and ok I will take off my shoes
is;-)
The nature of a loop is dynamics, placing the case within the loop
http://www.pcforge.com/WitangoGoodies.htmto me not intuitive but is required for a compiler.
I am just going by experience and IMHO I will take dynamics over compiled.

There really is no increase in code. I do this all the time in a single
conditional statement like:
for x = 1 to 10
select case x
case 1 field_1 = "some value" case 2 field_2 = "some value" case 3 field_3 = "some value" case 4 field_4 = "some value" case 5 field_5 = "some value" case 6 field_6 = "some value" case 7 field_7 = "some value" case 8 field_8 = "some value" case 9 field_9 = "some value" case 10 field_10 = "some value" next x
There are other ways also, this is the simplest. Another way is to build an array of objects, and loop through them.
I think you underestimate the level of performance gain you get
Especiallyyou compile versus interpret on the fly on complex tasks.
Iyouprocessing loops. I will do a test and get back to this with some results.

On one hand you have the quicker run speed but on the other hand

There is no easy conversion of code and mindset between them.

dynamic referencing a table is one thing, that should be ok. What
forwouldmean is referencing an object dynamically like you can do with javascript/flash with the eval() function.
For instance, in javascript/flash, if you have a set of fields, named field_1, and field_2, and so on to field_10, they could be referenced dynamically like so:
for x = 1 to 10 eval("field_"+str(x)) = "some value" next x
The same could be done in witango with a bunch of arguments, <@arg field_1>, and so on.
<@for start=1 stop=10 step=1> <@addrows local$newArray <@arg field_<@currow>>> </@for>
I don't believe this could be done in a compiled language. You
have to use a select case method or build an array of objects or something.

If you can make java bytecodes though and then use gcc to make

I've been kind of wondering about this since With said you could make

Just wondering if could expect any and all code to work the same whether it was tango or java bytecodes.

Just because our tafs would be compiled in some native format,
mean we would have to start worrying about things garbage
The compiled tcf would would have in/out points and process data within. It would run within the memory space of the witango server, and the server would handle the garbage collection and the nasty stuff. The main benefit would be that complex methods in a tcf would not be scripted, but compiled so that there would be no tag processing and the other performance drags that are inherant with an interpreted language. It would mean, though, that certain things you can do in a tml
languagetaf,
you could not do, like dynamic referencing.
