Hi Bill, I've figured it out, but have run into a new problem. I'm trying to get the history of EPS and Sales from the QP3 data, which are arrays. I didn't want to be this specific because I realize others don't have QP3 and I wanted to phrase my question in general terms that I think would work with all arrays. I think if you run this code on any array you should come up with the same error I got. Would you mind looking at it and giving your input? EPS=GetExtraData("EPS"); b=BarCount; i=1; EPS0=EPS[b-1]; Sales0=Sales[b-1];
//CurrentQ-1 do { EPS1=EPS[b-i]; Sales1=Sales[b-i]; i++; } while (EPS1==EPS0 AND i<b); //CurrentQ-2 //i=1; do { EPS2=EPS[b-i]; Sales2=Sales[b-i]; i++; } while (((EPS2==EPS0) OR (EPS2==EPS1)) AND i<b); //CurrentQ-3 i=1; do { EPS3=EPS[b-i];
Sales3=Sales[b-i]; i++; } while (((EPS3==EPS2) OR (EPS3==EPS1) OR (EPS3==EPS0)) AND i<b);
There's more, but you can see the general pattern from these three. The EPS array is set up so that each bar for a quarter has the same EPS value. When a new EPS comes out, the EPS changes (ideally; since I'll only be looking at stocks where EPS increases, I don't care if the code mistakes a new EPS for an unchanged EPS). I step back through the array to search for a different EPS.
This code works fine, but I would prefer that "i" continues counting up rather than reseting (as I've done with the "i=1;" line before each do loop). The problem with this is that the do loop checks the condition /after/ running the "EPSx=EPS[b-i];" line. So, when it hits a stock with few bars, the code errors out with the "outside 0...
(barcount-1) range" error. Is there a way to put a conditional statement in before the "EPSx=EPS[b-1];" line so that if "i" is greater than the barcount, then EPSx is null, or 0? I've tried changing the "EPSx=EPS[b-i];" line to "EPSx=iif(i>b, 0, EPS[b-i];" but that still errors out. Maybe there's something more basic I'm missing. Thank you, for your help. Cato

work for me. I was hoping to use the code in an exploration, and I
think this code will only give me the data in a debugger window,
correct? I tried assigning the _Trace calls to variables, and
then
displaying that variable with AddColumn, but of course that doesn't
work. I'm too programming ignorant to know why.

only wish I had some way of calling up a value from an array and
assigning that value, and only that value, to a variable.

You are welcome. sorry it isn't what you need.
Ref() does produce an array, the original one shifted by a certain amount.
If you can describe what you are trying to do, very exactly, in
English, I am sure the code would not be too difficult.
