I wonder if the problem isn't with this data step, but with some previous
step. The "NOTE: SCL source line." that appears in the log right after the
data _null_ statement leads me to believe that something else funny is
going on.

Actually, the order of the statements is not Paul's problem. I'm running
8.2 on W2K and the code works fine. In fact, it even works if the set is
never executed at all, and that because nobs is set at compile time.
110
111 data _null_;
112 put nobs=;
113 stop;
114 if 0 then set a nobs=nobs;
115 run;
nobs=1
Now, do I have a solution for Paul? Nope. :-)

Hi Paul,
Mostly we think most coding elements getting
processed at runtime. If I recall, the NOBS
is one of a half dozen things that get set at
compile time before executing through the
runtime, and compile time parsing is top down
mostly so the asking for nobs hasn't happened
yet, thus moving the SET statement in front
of the CALL SYMPUT will get things going again.
data unit_campus;
a=1;output;
a=2;output;
a=3;output;
a=4;output;
run;
data _null_;
set unit_campus nobs=nobs;
call symput('nobs',nobs);
stop;
run;
%put &nobs;
Hope this is helpful,

I am running 8.2 and I get the error message below.
I am confused because I have run that routine in SAS 8.0
some months ago and it worked. Anything new in 8.2 that may be affecting
this?
Any pointers will be helpful
