files=['test1.fits','test2.fits',...] ; use e.g. file_search for this
sum = READFITS( files[0], /NOSCALE)
for i=1,n_elements(files)-1 do $
sum += READFITS( files[i], /NOSCALE)
writefits, 'sum_filename', sum

Both readfits and writefits depend on some other procedures from the
ASTRO library. Make sure you compiled them too.
