class=934273705-14042003>Steve,
Your
example makes sense yet does not seem to work for me. Else seems to be ignored .
Using the IIF this would simply be ......
<SPAN
class=934273705-14042003>a1=iif(c>ref(c,-1),1,0); I am certainly
missing something here.... your input appreciated..

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
