It usually is :)

I've just deleted the long winded response where I printed out every
line in my code that involves either a OPENW,lun,/GET_LUN or a CLOSE
statement...

Because I realised that before the above snippet of code I have:

OPENW,lun1,'flatB.list',/GET_LUN
OPENW,lun2,'flatV.list',/GET_LUN
OPENW,lun3,'flatR.list',/GET_LUN
OPENW,lun4,'flatI.list',/GET_LUN
OPENW,lun5,'bias.list',/GET_LUN
OPENW,lun6,'dark.list',/GET_LUN
OPENW,lun7,'light.list',/GET_LUN
OPENW,lun8,'fblight.list',/GET_LUN
OPENW,lun9,'blight.list',/GET_LUN

PRINTF,lun1,FORMAT='(A0)',Bflatfilelist
PRINTF,lun2,FORMAT='(A0)',Vflatfilelist
PRINTF,lun3,FORMAT='(A0)',Rflatfilelist
PRINTF,lun4,FORMAT='(A0)',Iflatfilelist
PRINTF,lun5,FORMAT='(A0)',biasfilelist
PRINTF,lun6,FORMAT='(A0)',darkfilelist
PRINTF,lun7,FORMAT='(A0)',lightlist
PRINTF,lun8,FORMAT='("fb",A0)',lightlist
PRINTF,lun9,FORMAT='("b",A0)',lightlist

CLOSE,/ALL

Redinfo is opened before the close,/all statement...

So I deduce from this that in the absence of a 'redinfo' to printf to,
IDL has printed to another open lun...

This is interesting behaviour, I would have expected a message telling
me that the file unit 'redinfo' doesn't exist?

Anyway, thanks everyone. Once again I air my ignorance and shoddy
bookkeeping skills public on the idl usenet group. I learnt something
though, which is always good :)
