+The SAVE subcommand causes PSPP to save the residuals from the fitted
+model to the active file. PSPP will store the residuals in a variable
+called RES1 if no such variable exists, RES2 if RES1 already exists,
+RES3 if RES1 and RES2 already exist, etc.

 The EXPORT subcommand causes PSPP to write a C program containing
 functions related to the model. One such function accepts values of
 explanatory variables as arguments, and returns an estimate of the
