Hi,

Thanks to you both for the help. I now realise that I should have specified
my problem a bit more...

I'd like to be able to distinguish between a line with no characters and a
line with just one space in it.

Here's what I tried but it gives the same result for both if statments...

  data _null_;
    infile temp;
    input;
    if put(_infile_,$char.) = "" then put 'Empty line';
    if put(_infile_,$char.) = " " then put 'Line with a single space';
  run;

Any further help would be great.

Thanks.
