Thanks to all for participating in the conversation.
I have already posted the questions to AB group and have received 2 answers
by Janeczko. Since my problems and the corresponding queries concern mainly
AB users, I suggest we continue on AB board unless other MS users from this
group express their interest in this thread; I think that so far it might be
useful, but it is getting too detailed.
I tried java because according to Janeczko, writing functions at AFL level
is possible with beta versions only; and as Chuck noted I don't have access
to betas since I am a trial user. Janeczko said that the new
v.4.40 in late June will incorporate AFL level functions. I will be patient.
Unfortunately I keep receiving errors, with the java version too,
no matter what I do. I have deleted both functions (the called and the
calling)
and I have re-created them from scratch. I have been careful with the
spelling
with names consistency, I think I have done just about everything:
It doesn't want to work. I get error messages all the time, but what is
more strange is that sometimes I get different error messages for the same
version,
or more than one (obviously each referring to a different module).
My last attempt resulted in these messages:
Source: Microsoft JScript runtime error
Line: 4 Char: 1
Error: 0 - Number expected
..and just after accepting my ... destiny a new one:
Method/function 'myFunction' call failed at line 3, column 86:
Graph0 = script.myFunction(O,H,L,C)
----------------------------------^
Anyway. In a few hours I will go back to AB board and post my next questions
(regarding also simultaneous arrows on the same bar despite the excluding
setting,
equity drops in dead trading zones and maybe some more).
I would be very helpful if any of you continued to participate in the
conversation.
Thanks again
Spyros

OK...I see now.
I like your version better since it moves more code to the saved afl file
and eliminates the requirement of declaring the function in all the formulas
that use it.
I got high-centered on the #include part. Couldn't see how you could make it
work without it.

The original post mentioned that Spryos already had the #include in his
code (see below), so I didn't repeat that bit. His (original) problem was
more to do with version number than a syntax problem. He would need a
fairly recent beta (4.33?) to be able to use functions this way. Since he
mentioned that he is a demo user, he is unlikely to be using a beta version.

So what part do you disagree with?
You used #include in the formula that called it, right?
Without #include it won't work on my machine.

CS...sorry to disagree with you....
I created a function...as Chuck stated ..in an empty IB window:
function myFunction(x1,x2,x3,x4)
{
return (x1 + x2 + x3 + x4) / 4;
}
Saved this as myfunction.afl
Then in an empty IB window I put the following:
#include "C:\Program files\Amibroker\Afl\myFunction.afl"
x = myFunction(Open, High, Low, Close);
Plot(X,"",colorRed,styleLine);
It worked.....

Please excuse me for cutting in...
I haven't been able to get Chuck's solution to access a function
within the
separate AFL directory either, until I used:
Saved within C:\Program files\Amibroker\Afl\myFunction.afl
return (x1 + x2 + x3 + x4) / 4;
That's it. Just one line. No brackets.
Now, within Indicator Builder, my formula is:
function myFunction( x1, x2, x3, x4 )
{
#include "C:\Program files\Amibroker\Afl\myFunction.afl"
}
A2=myFunction( O, H, L, C );
Plot( A2,"function example", colorRed );
Hit APPLY and it should work (with ver 4.36).
I had to insert the #include instruction since it doesn't appear that
AB
function commands will search the hard drive for the saved afl file by
simply stating
x = myFunction(Open, High, Low, Close);
AB will search for the called function within Indicator Builder, but
it
doesn't appear to out on the hard drive.
