Nonsense, works fine with arrays: Try
print,findgen(10),100,format='(11f8.2)'

Yes, using the format keyword is exactly what I was suggesting to do in
first place, but badly...!!!!
In any case, I think that should not work either if one of the
variables is not an array and if he is using a loop.
alternatively, he can avoid using the loop at all and just write:
openw,unit,fileout
printf,data[0],data[1],data[2],data[3],data[4],data[5],doy,
format='(....)'
where inside the parentesis he will put the right formatting for each
and everyone of the data...
actually, i think avoidind the loop will work also if he puts that doy
data at the end.....
bye bye

Alternatively you can uise formatted output suing the FORMAT keyword to
printf. Haje

Ooops...
I've just notices that you last variable: 'doy" is not an array,
while all the other 5 are. Is that right?
I think in this case what I've said above will not work either.
I am not awared of what Ben told you above, but if that does not work
either, ...here is anoother idea...
Why do not you save the "doy" variable separately from the other data?
I mean, something like:
openw,1,fileout
printf,1,doy
for m=0,M-1 do begin
prinft,1,data[0,m],data[1,m],data[2,m],data[3,m],data[4,m] ,data[5,m]
endfor
close,1

Hello,
I think you might need to specify the WIDTH keyword when you OPEN the
file. Try something big like 500.

You should better use
openw,lun,/get_lun, filename
and at the end
free_lun,lun
Because then you don't get into the trouble if somewhere a fixed unit is
already in usage.
If you add width as keyword you can setup a longer width as the detault one.
I am not sure what the loop is used for. Didn't you get the same result
by prinft,lun,data. Probably you only need to transpose?
Idl does not be case sensitive so you see me a bit surprised that's this
work. I would have bet against this
m=5
for m=0,M-1 do begin
For better coding I would suggest to rename M to n_from_what_it_is, and
to use i as increment var. But that's a question of reading/writing style.
