I don't want to be a pessimist, but I think you really want to be using
MatLab here. :-)

Cheers,

You need to read your data.dat into an IDL variable and then write it to FITS.
We need to know more about the format of your data.dat file before we can tell you how to read it. If it is a binary file, then you can use READ_BINARY()

im = read_binary('data.dat') ;Read data into variable
writefits,'test.fits',im ;Write variable to a FITS file 'test.fits'

You need to get writefits.pro from the IDL Astronomy library if you don't already have it.

Well, since you've given no information about what the data.dat file contains or what *TYPE* of fits file you want, it's truly impossible to answer your question without some snarky comment. Maybe you should tell us more about the data in the data.dat file, more about the structure of the output you'd like, and where exactly you're stuck. Just for good measure, also tell us is the data.dat file an ascii file or some other goofy thing. What precisely do you mean by "fits" file --- do you mean flexible image transport system used primarily in astronomy? We all need to be on the same page here, and you're not very forthcoming with information.
