Hello,
These for / while loops are IDENTICAL to those offered
by C / JScript
so any C / JScript book will do, including on-line
resources like:

Hello,
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 on arrays,
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.

Re: [amibroker] AmiBroker 4.31.0 BETA Examples
Hi Ken,
I think the concept of loops and if-then-else is the
same in all languages. 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 of using AFL syntax. You would
probably use it mostly for iterating your arrays if you wanted to do
that. Here is a simple pseudo-code - try coding it in
AFL:
For (SecondBar to LastBar)
If (Today's Close > Yesterday's
Close)
MyArray = 1
Else
MyArray = 0
Plot MyArray
Of course, please feel free to ask for
help!
Steve
