what happens to SAS special missing value codes in SPSS?

[lisa-23]

Hi - I'm not an SPSS user, but am trying to figure out what will happen to
SAS special missing value codes when a SAS dataset is opened in SPSS. For
instance, if I assign x = .z in SAS and then someone opens the dataset in
SPSS, what value will x have in SPSS?

thanks,
Lisa
