Let's say I know the exact location of a peice of data

Let's say...you don't. :) I tell you what, you tell me how you know this, and I'll tell you how to do it. You won't like the answer.

For starters, you can't take a string and get a viable reference from it. Well, almost. It involves XS programming and that's torture for most people.

What'cha got in memory? How do you know it's there? Is this part of your process or someone else's? Is this a machine API (BIOS?)? Inquiring minds want to know.
