How to read variable names in a SAS data set?

Question

Are there any statements\\functions capable of get the name of variables? Preferrably putting them into a column of another data set, a text field or a macro variable.

Answer 1

You can also use a datastep and array functions, e.g.

data colnames ;
  set sashelp.class (obs=1) ;

  array n{*} _NUMERIC_ ;
  array c{*} _CHARACTER_ ;

  do i = 1 to dim(n) ;
    vname = vname(n{i}) ;
    output ;
  end ;
  do i = 1 to dim(c) ;
    vname = vname(c{i}) ;
    output ;
  end ;
run ;
