No its not working that way i tried it.
actually I have :
aa=mrdfits('spec-3819-55540-0876.fits',1,h)

IDL> help,aa,/str
** Structure <a469504>, 8 tags, length=32, data length=32, refs=1:
FLUX FLOAT 12.7965
LOGLAM FLOAT 3.55550
IVAR FLOAT 0.0395813
AND_MASK LONG 0
OR_MASK LONG 851968
WDISP FLOAT 1.55296
SKY FLOAT 4.95728
MODEL FLOAT 18.1191

now I only want to change value of aa.FLUX.
doing mwrfits,'spec.fits',aa,h as you suggested is changing value of all variables. Is any one getting my problem???
