Photoshop JSX — How do I copy arbitrary text to the clipboard?

Right now I am using the prompt command as a workaround to copy arbitrary text out of my JSX script in Photoshop.

prompt("to copy",(horizontalcenter.toString()) + ", " + verticalcenter.toString());

And that is giving me the information that I want. The "to copy" just gives the title, then the information I want to copy out of Photoshop is in the prompt box already selected. So all I have to do is hit control C, go to Notepad++ where I need this information, and hit control V.

It works, but it could be faster. There has to be a way to copy this information out of Photoshop straight to the clipboard, no?
