st: replace observation values

[Nikolaos Pandis <npandis@yahoo.com>]

Hi to all.

Would you please help me with the following question:

In a dataset under one variable I have two names for the same type of observation (ie CASE-CONTROL AND CASE_CONTROL). 
How would I change all in CASE_CONTROL without having to do each one individually?

Thank you very much.

Nick
