I am importing some CSV sheets with 60+ variables and the author used ? for missing values so they are imported as ?. How can I simply set all ?s to missing without having to write 60 if-thens?

Something like this.

data want;

  set have;

  array num_vars _numeric_;

  array char_vars _character_;

  do over num_vars;

    if num_vars=? then call missing(num_vars);

  end;

  do over char_vars;

    if char_vars='?' then call missing(char_vars);

  end;

run;

Thanks. That works. The only problem is that num vars are assumed to be character var during import because of instances of ? in them.

Any thoughts how to turn them back to num var after correction?
