Subject:      Unfamiliar CALL EXECUTE syntax
Content-Type: text/plain; charset="iso-8859-1"

I copied the following code excerpt from a message posted back in 7/97 by
Bruce Kayton and it works, but I can't explain it, having never seen the
!!objname!! syntax used here.  Could someone please explain what is
happening here?  The code looks like:
 
data _null_;
  set sashelp.vcatalg (where=(libname='WORK' and memname='GSEG'));
  call execute('%replay('!!objname!!');');
run;
 
It goes through the sashelp.vcatalg table and pulls off graphics entries,
and then eventually calls a PROC GREPLAY to replay each entry.  I think the
catalog entry name is being passed to !!objname!!, but as I said before,
I've never seen that syntax before, and I couldn't find it anywhere in the
on-line help.
 
Thank you very much in advance,
      Nancy
