    I want to import a data file that produced by spectrometer into
mathemathica and fit the data. The file is in text format ("data.txt").
The data in the file is characters: first line:some descriptions.
second line: 200, 45.5. third line: 201,44.3. and so on. If you open
the file "data.txt", you will see:
transmission ratio by UV-3150
200, 45.5
201,44.3
202,44.6
203,46.7
...
1,000,75.5
1,000,76.3

How to import these data in to mathematica 5.0 and plot the figure?
Thank you very much
