I need to find out If a Varible exists in the dataset . So for that I am
trying to do something like this
*If Not Missing (Aehfrml) then Cmdosfrm = Strip(Upcase(Aehfrml)); * Else
Cmdosfrm=" " ;
If %Symexist(Aehfrml) Then Do ;
If Not Missing(Aehfrml) then Cmdosfrm = Strip(Upcase(Aehfrml));
End ;
Else Cmdosfrm=" " ;
If Not Missing(Aehmddf)and Not Missing (Aehmdd) then Cmdostxt =
Strip(Aehmddf) ;
Else Cmdostxt
= "" ;
When I do Not Missing () does it checks if a variable exits or does have any
values ??
and Can I use %Symexist inside the datastep if not is there a call routine
that I can
