AM,
<p>I downloaded the modules from CPAN... Figured out how to debug from a browser... Uploaded the modules to Yahoo into a directory I created /lib... put a statement into my perl script... </p>
<p> use lib "./lib"</p>
<p>added additional module dependancies... and now it works, I can get historicals directly from yahoo, and print it right to the browser.</p>

<p>Awsome, the power of figuring this out. Thank you so much for the great hints.</p>
<p>My next task is to perform some math on the data and then print the original data plus calculated columns back to the browser. There are modules out there "Stockmonkey" Math::Business::xxx that does some common financial type things to the data. But it uses a database behind the calcs, and I think I must avoid that. The way this is going to look in the end is something like this:</p>

<p>So my question is something like this: I belive I need to use an array of arrays (sorted by first element - Date) and append my calcs to the end of each array. (one line/array is a list of elements that I have to store in memory) Then I print it sorted (reverse) to the browser. Am I on the right track in that thinking? I'm worried about building a large data structure in memory on a server I don't own. I'm wondering if a module already exists that may do some of this already? And I don't know, what I don't know, so I was hoping to run this bye you first. Any thoughts?</p>

I can see it in c code like this...
for(i=0;i<250;i++){
for(j=0;j<20;j++) {
array\[i\]\[j\] = {do some math};
}; //end of for
}; //end of for
see what I mean? make sense?
