[EquisMetaStock Group] cum(1) function

["dpleydel" <dpleydel@xxxxxxxxxxxx>]

Hi 

I've looked at the primer but I still don't quite get what this 
function is doing.

for example I've seen it used in a this this regard:

buy:=If (some boolean test),cum(1),0)

Does this mean it's like this
If TRUE then
buy = buy + 1;
else
buy = 0;

Thanks
David
