Perhaps you want to recode them with special missing values?

. replace var1=.a if var1==99999
. replace var1=.b if var1==77777

or better:
. recode var1 (99999=.a) (77777=.b)

This will "treat" them as missing in calculations but you do not loose the fact
that .a means "unknown" and .b means "refused to answer".

>Hi, I have continuous variables that are coded 99999 or 77777 for unknown or refused to answer. How do I handle this? I don't want to treat them as missing, if possible.
