Hi,
 
Try using the obs=0 and noreplace system options and then pickup the SYSRC
macro variable after the datastep or proc has run;
e.g.
options obs=0;
options noreplace;
data out;
  set temp;
  if=&userif;
run;
 
You can pick up the SYSRC macro variable in AF with the following code:
rc=symget('SYSRC');
 
The obs=0 option specifies that 0 observarions are read in from the input
dataset.
NOREPLACE tells SAS not to overwite an existing SAS dataset with one of the
same name.  If you are creating a new datastet, it will be created wath all
the variables,
but with 0 observations.
 
I havn't tested this, but it should work.
