Scripts are the functions/statements like for, if, while that are normally
associated with scripts.

Subject: [amibroker] Re: For loop help
Dimitris, Dingo, Herman, Graham,
Thanks to all for your replies. The trick that did it was the
SetBarsRequired(10000,10000);
statement. What is confusing is that the explaination for this
function says that it is not needed if you are using pure AFL, only
if you are writing scripts or dll's. Anyone have an idea about this?
For reference, the statement
for(i = StartDate; i < EndDate + 1; i = i + 1)
does work. The i < EndDate + 1 stops the calculation at i = EndDate.
Finally, the PHigh[i] statement can be PHigh (without the [i]) if you
only use PHigh as a scalar in your later statements within the loop.
The code works fine either way.
Dingo, I'm confused that the code ran for you the way it was
supplied. I am using V4.50. Are you using a later beta version?
Thanks again for your help.
Bill
