|The SCORE Procedure|
The VAR statement specifies the variables to be used in computing scores. These variables must be in both the DATA= and SCORE= input data sets and must be numeric. If you do not specify a VAR statement, the procedure uses all numeric variables in the SCORE= data set. You should almost always specify a VAR statement with PROC SCORE because you would rarely use all the numeric variables in your data set to compute scores.
