Subject:      What infile is my current input reading from?
Content-Type: text/plain; charset="iso-8859-1"

And now for something completely different!

Suppose I'm being given the name of a file which is to be
%included in an overwhelmingly convoluted SAS data step. All I
know is this file's name, let's call it "exit_point.sas" .

I know that basically the data step is designed like so:

  data ...;
    infile <varying_infile_name_here>;
    input ... ;
    %include exit_point.sas;
  run;

How can I determine what filename the input statement is currently
reading from?

Such a simple question and yet I don't see the answer?
Am I just overlooking the obvious?

(And to cut down your enthusiasm: I need an 8.2 solution if there
is one. For the sake of education I will also take a 9.1.x one)


Thanks alot in advance
