Create a macro to standardize a data set with a given value for mean and std.

%macro standardize;
%let dsname = %sysfunc(dequote(&dsname));
%let colname = %sysfunc(dequote(&colname));
proc standard data = &dsname mean = &MEAN std = &STD out=_out;
   var &colname;
run;
data &dsname;
   set_out;
run;
%mend standardize;
