So, what I think I'm hearing you suggest -- is that rather than trying to get yahoo to install a perl module into it's /usr/bin/perl structure on all their web servers -- it's possible to build a stripped down perl with all the modules required built right into it, and upload that package and all the related files somewhere in the path I own, and then somehow point to that build rather than the default for the yahoo server?

Now to be more specific, I build something like citrusperl on my laptop or wherever, add the CPAN perl modules I need to that, then use cavapackager to build a binary package that I can upload to somewhere in the tree to my site? Then I guess I change the path to the new perl instance in my script to use my version of perl somehow? I anticipate that I would need some symbolic links at worst...

Is that the idea? -- thank you for sticking with me on this by the way, I do appreciate it...

It seems like I could install cygwin somewhere without perl, then install citrusperl, cava package it, upload it to yahoo, test it, and keep the cygwin environment because I will probably wish to add functionality over time. Then I just refresh the upload whenever I add a non-standard module, and back in business for more? correct?

Um, kinda, the general idea, yes :)

First idea I would try is to read the docs for your hosting plan :) they explain how/to install what, what you're allowed to install, things like that, so you don't waste your time or piss them off :) -- look above, pair.com offers hosting plans that allow you to install any perl you want :)

Then, if have shell access, use cpan/cpanm ... with INSTALL_BASE to install prerequisites

Or install a modern perl (like 5.14/5.16) with all prerequisites

If no shell access, use http://cgipan.sf.net/ to do the same ( linked via Installing modules without root and shell via Yes, even you can use CPAN )

cpanminus is zero config cpan replacement, might make the installing go smoother

If and only if the above directions fail, go through the hassle of installing a virtual machine, with same/equivalent operating system as what your webhost has,

Then you can install whatever binary perl distribution you want (strawberry/activestate/citrusperl ), install all the modules you need,

Then either pack a single executable using perlapp, par/pp, cavapackager

Or pack a complete distribution , either DIY whole directory tree with activeperl/Strawberry, or use citrusperl, it comes with a nice GUI for creating distributions

perlapp supposedly can target other platforms, doesn't require a virtual machine, but still requires all the prereqs to be available for that platform via ppm , and there might be some licensing issue -- I've no experience with this

AM,

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...

use lib "./lib"

added additional module dependancies... and now it works, I can get historicals directly from yahoo, and print it right to the browser.

Awsome, the power of figuring this out. Thank you so much for the great hints.

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:

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?

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?
