%macro check(dsName = );
%let dsid = %sysfunc(open(&dsName, IS));

%if &DSID = 0 %then
%put %sysfunc(sysmsg());
%let nlobs = %sysfunc(attrn(&dsid,NLOBS));

%put No of Observation in dataset %trim(&dsName) : %trim(&nlobs);

%let rc = %sysfunc(close(&dsid));

%mend;


%check(dsName = );

dsid, rc, ??? have u defined it, have u run it does it work does it return the number of observations i want the number that's imp. "a macro to determine the number of obs in a data set"

the log

In

%check(dsName=);

you specifically submitted an empty string to the macro, so no dataset could be found.

Supply a valid dataset name, and the macro will work.

 

Inform yourself about how parameters are passed to macros.
