title: SAS: Automatically pass variables from proc reg to proc score
body: <p>I am running multiple interations of sequence containing proc reg and proc score. How do I automatically pass predictors from proc reg to var list in proc score? I know in proc reg, outest outputs a dataset that contains all the variables with predictors being populated with estimates. In that dataset, non predictors have a missing value. Does proc reg allows for an easy way to capture just the predictor variables?</p>
  
  <p>Thanks!</p>
