If you only have access to the IDL VM, I don't believe that you are going to be able to modify FITS files. Or is it that you have a license and are trying to write a VM application?

Anyway, if you have a FITS header (e.g. read in with headfits() ) then the following little program will convert it to a structure (by using a hash as a intermediary). --Wayne

function fits2struct,hdr
; struct = fits2struct(hdr)

keywords = strmid(hdr,0,8)
hashfits = hash()
foreach key,keywords do hashfits[key] = sxpar(hdr,key,/silent)
return,hashfits.tostruct()
end
