Hello sid,

David Fanning has a great tutorial on his site explaining how to read
ASCII data files: http://www.dfanning.com/tips/ascii_column_data.html
(Make sure to check out the rest of his site, it's a great IDL source)

After you have your data as an array or structure, you can use a
procedure like MWRFITS or WRITEFITS to save your data as a FITS file.
Information on reading and writing FITS files using the IDL Astronomy
Library is available here: http://idlastro.gsfc.nasa.gov/fitsio.html

Hope this helps,
~ Aram Panasenco
