First, you must create the label formats with proc format using a value statement. Next, you attach the label format to the variable with a format statement. This format statement can be used in either proc or data steps. An example of the proc format step for creating the value formats, forgnf and $makef follows.

PROC FORMAT; VALUE forgnf 0=”domestic” 1=”foreign” ; VALUE $makef “AMC” =”American Motors” “Buick” =”Buick (GM)” “Cad.” =”Cadillac (GM)” “Chev.” =”Chevrolet (GM)” “Datsun” =”Datsun (Nissan)”;RUN;
You may include any number of value statements to create label formats as needed. Since make is a variable that contains character values, when you define the formats for it you have to precede the format name with a $ so the format name becomes $makef. Additionally, for character variables the values of the variables must be enclosed in quotes.
