Writing Pixel Color Information to a File?

In Photoshop, using the image analysis tools, one can determine various parameters of a selection, like area and mean gray value, and write these values to a text file.  Is there a way within Photoshop to determine the hexadecimal color value of a pixel and write that value to a file?  I want to query and record dozens of points, more than is practical to do with the Color Sampler Tool and jotting down the values.
