Hi,

I adapted your snippet a bit (see below) and it seems to work fine on my
system { x86_64 darwin unix Mac OS X 7.1 Apr 21 2009 64 64}

My guess is that upstream of that code block the LUNs are getting swapped.

Cheers,
Ben

PRO testme

OPENW, lun, "lun.txt", /GET
OPENW, redinfo, "redinfo.txt", /GET
GET_LUN, lun2

nwestframes = 2

IF nwestframes GE 1 THEN BEGIN
PRINT, "lun2= " + STRTRIM(lun2,2)
PRINT, "lun= " + STRTRIM(lun,2)
PRINT, "redinfo= " + STRTRIM(redinfo,2)
OPENW,lun2,'lun2.txt'
PRINTF,lun2,"print to lun2"
CLOSE,lun2
PRINTF,lun,'print to lun'
PRINT,'print to command line'
PRINTF,redinfo,"print to redinfo"
ENDIF

FREE_LUN, lun
FREE_LUN, redinfo
FREE_LUN, lun2

END
