Anthony,
I want to be able to create a function that will return a number to another
function that calls the first one. It doesn't really matter what myFuction
returns exactly. For simplicity, suppose that what I want to get is
(O+H+L+C)/4. I do know that this is so simple that it doesn't need to be a
separate function, but let's accept that this is what we want to do.
Actually I had problems with this one too!
Although I have never used java sript before, I thought I could make such a
simple script by just reading the examples given. So, this is what I did:
First I created a function named "myFunction" like this:
EnableScript("jscript");
<%
function myFunction(x1,x2,x3,x4)
{
return (x1 + x2 + x3 + x4) / 4;
}
%>
I saved it in C:\Program files\Amibroker\Afl
Please notice that I have checked that a function called "myFunction" exists
there indeed!
Then I tried the calling formula:
#include "C:\Program files\Amibroker\Afl\myFunction.afl";
script = GetScriptObject();
Graph0 = script.myFunction(Open,High,Low,Close);
The problem is that each time I click 'Apply' I get this error:
Method/function 'myFunction' does not exist at line 3, column 96:
Graph0 = script.myFunction(Open,High,Low,Close)
----------------------------------------------^
1. I don't understand. I do see "line 3", but where is "column 96" in the
above code?
2. "doesn't exist"?! But I do see it! So, what is the mistake I have made in
the above formulas?
3. The program freezes all the time and I have to shut it down and re-run
it.
4. This is not all. So far I have not managed to get a "Points-Only" test,
according to the instructions given. The tester keeps buying and selling
dozens of shares or contracts depending on the equity, regardless of what I
have written in the code.
5. Sometimes I get rubbish on the main chart.
Maybe I have to re-install the program; maybe it is the RT (eSignal)
version..??
Is it the "demo"? Who knows..
So, in case you can help with some of the above, I will be very much
obliged.
I will also try once more with the AB board, later.
Thanks
Spyros

Spyros,
If you want to give an example of what you are trying to do...then a more
helpful solution
can be given...

Anthony and Kevin and Chuck thank you for your replies.
Chuck:
1. Obviously
myVar = myFormula()
is not enough because it doesn't work [although I am trying with version
4.30 (the latest?)]
I wouldn't mind to have to write a couple of lines including #include
directives etc. as
Anthony suggests (in fact, I had already tried that several times in the
past) but I usually get errors.
That's why I keep asking and trying. I have already read Janeczko's java
script and VB examples
and a few messages on the AB board. Sometimes the #include solution works,
other times
it does not. I get unexpected and inexplicable errors.
2. I asked on this board because the AB conversation was brought to this
board (not by me anyway).
BTW my opinion is that such conversations are not exactly off topic because
I guess that the
members of this group are much more than just MS users. Some of them have
already tried
other software (AB included), some have already asked questions about such
software and most
of us would like to have some elementary information about ... the rest of
the world.
3. As I said, in the past I had directly asked Janeczko about these problems
but I got no answer.
Yes, he had rapidly replied to my first message, but as the problem
persisted, I had to ask again.
This time he did not reply. A few days ago I searched the AB database for
relevant messages.
I found I few, among which some replies by Janeczko. I must say that they
were not very encouraging.
So, my impression so far is that neither AB programming nor the
communication is free of problems.
Please don't missunderstand me. I still believe that AmiBroker is an
excellent program. And as far as
programming is concerned it is much more powerful than Metastock, which for
different reasons
is also an excellent program. I am just saying that both programs have their
cons and unless
the function-calling problem is solved for good, this IMO will be a major AB
drawback.
Anyway I will make a new attempt with the AB group.
Thanks again
Spyros

It's even easier in AFL. Just say:
myVar = myFormula();
Even better than MS, AFL will let you pass values to the "other" formula as
with this example:
myVar = myFormula(Open*1.1);
A lot of people are willing to help with AB/AFL questions, but feel awkward
answering them on this board. If you ask questions like this on the AB
board, you will get a quick reply. In fact, you will get dozens of replies.
