If your variable is a string variable type

. replace varname = "CASE_CONTROL" if varname == "CASE-CONTROL"

where varname ist the name of your variable. 

If it is a numeric variable with value labels attached to it use the
respective numerical numbers instead of the strings, or type

. replace varname = "CASE_CONTROL":varnamelabel ///
       if varname == "CASE-CONTROL":varnamelabel

where varname is the name of your variable and varnamelabel is the name
of the value label attached to it. 


Many regards
Uli
