4.31.0 BETA ExamplesAnyone, Ok, a very simple
example..... x=IIf (H >Ref(H,-1),H,L); this would
result in a line touching eitherthe h or low of each bar based on the
condition.if (H >Ref(H,-1))y = H;elsey
=L;Plot(y,"HL",colorYellow,1);Plot(C,"",4,styleCandle); rather
than evaluating the condition on a bar by bar basis this looks
tolastvalue(h) to determine Y for the whole chart. How would I use
theif/else syntax to copy IFF? Jayson -----Original

ExamplesActually let me clarify something:condition expression=
i<barcount; means do the
loop as long asi< the current barcount (like cum(1))?? YESthis
would actually be something like do the loop as long as i<barcountwhere
barcount = lastvalue(cum(1))Regards,Peter-----Original

ExamplesHello Jayson,myema[ 0 ] = close [0];Amibroker
uses zero based arrays meaning that the first record in anarray is at the
0 position. Basically this just gives a value to thefirst myema
array. The zero position is the first data record of theclose
array.for ( init-expression ; cond-expression ; loop-expression )
statement init-expression=
i=1; means we start the
loop with i=1? YEScondition expression=
i<barcount; means do the
loop as long asi< the current barcount (like cum(1))?? YESloop
expression= i++ means i+i+i ??????????
basically this justmeans i = i + 1Hope this
helps,Peter-----Original Message-----From: Jayson

agree. for/while/if-else + array access is coveredon 3 or 4 pages of any
C/C++ book So this is actually less than 1% of entire C/C++

4.31.0 BETA ExamplesHi Steve,C++ is definitely not required
to program in AFL;it would be an overkill! C++ covers maybe 10
times more stuff than AFL.The new stuff in AFL is easily learnt within
2 hours.Simply ask the people here. UM -----

[amibroker] AmiBroker 4.31.0 BETA ExamplesHi Jayson, Sorry to
offer the help and then not be around to follow through on it.But, Monday
seems to roll around almost every week these days, and thenits off to work
again. Better for you though - TJ filled in for me :
-) I'm not sure what kind of book you would like, but since
TJ seems tofollow C++ syntax, I can recommend a C++ book that I found to
be verygood (pretty big though - over 1000 pages). It is very thorough and
easyto understand - definitely geared for beginners in my opinion. It
is"C++ Primer Plus" by Stephen Prata. I think you could probably just
readup on the items you are interested in if you aren't interested
inlearning the whole language. Be careful because it seems that there
area couple of other C++ books that call themselves "primers",
but aredefinitely NOT for beginners. Especially stay away from
StanleyLippman's book, at least until you have some experience (take it
fromme....please!). Steve ----- Original Message

ExamplesHello, While IIF works on ARRAY, if/else
works on INDIVIDUAL number/boolean (element of the
array). Therefore you should write either a1 = IIF(
C > Ref( C, -1 ), 1, 0 ); (or even: a1 = C > Ref( C, -1
); or iterate: for( i = 1; i < BarCount; i++
){ if ( Close[ i ] > Close[ i - 1 ]
) a1[ i ] = 1;
else a1[ i ] =
0;} It is important to understand that IIF is a
FUNCTION that works onarrays,while if/else is control flow
STATEMENT.Function just evaluates all arguments and returns
value(s)Control flow statement changes program flow. This is
fundamental difference. Best regards,Tomasz

ExamplesSteve,Your example makes sense yet does not seem to work
for me. Else seems tobe ignored . Using the IIF this would simply be
......a1=iif(c>ref(c,-1),1,0); I am certainly missing something
here.... yourinput

ExamplesHi Ken, I think the concept of loops and if-then-else
is the same in alllanguages. I imagine you could read up on
it at many websites (e.g. -MSDN scripting site). Once you grasp the
concept, it is just a matter ofusing AFL syntax. You would probably use it
mostly for iterating yourarrays if you wanted to do that. Here is a simple
pseudo-code - trycoding it in AFL: For (SecondBar to
LastBar) If (Today's Close > Yesterday's
Close) MyArray = 1 Else
MyArray = 0Plot MyArray Of course, please feel free to ask
for help! Steve ----- Original Message -----
