Hi,

ok, you have 2 solutions. The first one is to create an array holding
your c's values... so you have c1 = fltarr(x,y), c2 = fltarr(x,y) etc,
you would end up with c = fltarr(x,y,nbBands). Then you can use C in
your loop (writeu, lun, c[*,*,i]) . Alternatively, you can use an array
of pointers (if you don't have enough memory).

Otherwise, have a look at SCOPE_VARFETCH It will allow you to retrieve
the content of your variable.
