Thanks for your reply. I am interested in stellar spectra reduction. I
reduced my data from 2-D to 1-D and I did the wavelength calibration
using iraf. Now, I would like to do the last step which is the flux
calibration. Does the question make more sense now?

Your question is far too general for anyone to give a useful
answer. What type of spectra? -- astronomical?, laboratory?.
What type of calibration sources are available? What wavelength
regime are you using? What type of calibration? -- absolute flux?
or wavelength? Are the spectra slitless? High or low
resolution?
In general, IDL is well-suited for this sort of work, since it is easy
to adapt it for particular instrumental signatures.
One example of a very well-documented IDL spectral reduction package
is the one for the Solar-Stellar Spectrograph at
