Thanks for the reply. I do not want to drop the entire
observation as it has nonmissing values for some other
variables. For examples,
var1 outcome1 var3 var4
obs1 1 2 7 99
obs2 99 99 3 1
obs3 0 2 5 4
obs4 1 0 99 99
For analyses of var1 , i want to include obs1, 3, 4
and for var 3 - obs 1,2, and 3.
However, when i run the regression for outcome1
against var1, var3 or var4, I do not want the "99" to
be included as a legitimate coding for those variables
and hence influence the odds ratio estimate.
Hope that clarifies my question a bit.

Just recode 99 to missing, as some other people have advised you to
do. (You can use -mvdecode- or -recode- or -replace-.)
