How can I separate my data set easily based on station names

I have a dataset with a number of ground stations with a corresponding x, y and z coordinate, a week number and a year number. I wrote a program that removes outliers, fits a curve, plots the series etc etc for a single station. However I have this enormous data set with a weekly value for every station for 5 years.

An example of a data line is:

ALGO 45.95580042 -78.07136855 200.911047 12 2007

The question now is, is their an easy way to import the data and separate and sort the data so that I can run the program for all stations separately?

I hope that I explained the purpose of my question for it is a bit difficult to write down.

Thanks in advance!

This is the place to use a table and categorical arrays. Start at

for tables and then look at the categorical arrays and the examples converting character variables to categorical.
