Hello,
It *DOES* work, but as I explained in the Manual,
in the chapter I pointed out in my previous
reply:
"WriteIf in fact does not "write"
anything. The name is misleading but it is left
for easy translation of MS
formulas to AmiBroker.
WriteIf is just "TextIIF" it RETURNS string value
depending on condition.
In commentary window, statements
evaluating to STRINGS on global level
are displayed in
the output window. However if you do the same inside the FUNCTION
it is no
longer in global level (it is on LOCAL, FUNCTION level).
function comment(indicator)
{
printf( "\nComment...\n" );
printf( WriteIf(1, "TrueText", "FalseText") );
printf(
WriteVal(indicator) + "\n" );
}
"
In other words, STRINGS expressions that are on global level, i.e. NOT
surrounded with { }
do display in commentary, but those on tested level don't.
All new codes should use printf().
The behaviour outlined above is for compatibility with old formulas that
were written
in ancient times, when there was no user-defined functions, no printf() and
no if-else.

Subject: Re: [amibroker] Problem with
Status("actionEx")
I'm afraid that I haven't made myself
clear about what I really want to know. So --
What I really want to
know is WHY my snippet, containing Status("actionEx"), doesn't work.
What is it
that I do not understand about Status("actionEx")? I am not looking for
alternative ways to work around a problem that I do not understand, but I am
looking to understand the problem in the first place. Status() appears
to me to be an extremely useful function which I want to learn ALL
about.
Thank you.

Re: [amibroker] Problem with Status("actionEx")
Mmm, I?m not sure what to tell ya. Only TJ can give you
a definitive answer. I have an idea why, but I can?t prove it. I like
experimenting with AFL and discovered this one a while ago. So, all
I have is results through observation and my acceptance of the results.
I can tell ya to read up on the WriteIf function. It
will give you a clue, especially TJ?s comments, and an alternative to your
code. You can eliminate the IF statement altogether and use WriteIf along
with WriteVal or NumToStr for the conversion.
Something like this:
WriteIf(Stat == Indicator OR Stat == Commentary OR Stat
== aToolTip OR Stat == aInterpret, WriteVal(Lowbody, 1.3), "");
or
WriteIf(Stat == Indicator OR Stat == Commentary OR Stat
== aToolTip OR Stat == aInterpret, NumToStr(Lowbody, 1.3), "");

That works
fine!!
I don't like to "look a gift horse in the mouth", but, how
did you know? I've looked through AB Users Guide and Help file and
can't find where that might be explained. If you've got the time,
I would sure like to know, to get a better understanding of what I am
doing.
Thank you so much.

Use Printf instead of WriteVal.

Thank
you for your suggestion. However, I know I don't need it for
just the snippet displayed.
This is from a much larger
program where I wish to disable the display in Indicator,
Commentary, etc., if/when some other actions are performed.
When I post a question, rather than post my entire code, I
try to break my code down first to just that part that I do not
understand, and post it.
So my question remains.

remove the if line altogether, you should not need

Without the 'if()'
restriction below, all of the text and WriteVal(), etc. is
displayed in the Interpretation Window as it should be.
However, when include the 'if()' restriction it is no longer
visible. I believe it should still be visible because of
the "Stat == aInterpret" inclusion in the 'if()'. If all
plot() statements a within the 'if()' restriction, the charts
are drawn as expected.
What's
wrong?
Indicator =
1;
Commentary = 2; aToolTip = 16; aInterpret =
17;
Stat = Status("actionEx");
if(Stat ==
Indicator OR Stat == Commentary OR Stat ==
aToolTip OR Stat == aInterpret){
"Lowbody = " +
WriteVal(Lowbody, 1.3);
"Highbody = " +
WriteVal(Highbody, 1.3);
"risk = " +
WriteVal(risk, 1.3);
"ATRcond =
" + WriteVal(ATRcond,
1.3);
"%risk/Equity = " + WriteVal(100*risk/myE);
}
Would
appreciate any help I can get.
Thanks.
