Subject: Macro question
Content-Type: text/plain; charset="us-ascii"
Could some one explain why the following macro doesn't work?
The problem is with variable emplty03.
%if %sysfunc(exist(&tribe2.nhanes03))=0 %then
%if &emplty03=1 %then
%put data not available;
A character operand was found in the %EVAL function or %IF condition
where a numeric
operand is required. The condition was: &emplty99=1 and
&emplty00=1 and &emplty01=1 and
&emplty02=1 and &emplty03=1
How could I check if a dataset is _null_?
I need to check if a dataset(one) is _null_, I do the following:
If one=_null_ then ...
It doesn't seem to work that way.
