Proc Freq Warning

[Mur]

Hi All,

I am running into this warning message with proc freq.  I am not sure what's causing this warning message.  Below is the code and the warning message.  Any help is appreciated.

proc freq noprint data=one;

where ST='';

by STDATE;

table hms5*STDATE/out=xxx5;

run;

WARNING: Variable STDATE already exists on file WORK.XXX5.

NOTE: There were 4390 observations read from the data set WORK.ONE.

      WHERE ST=' ';

NOTE: The data set WORK.XXX5 has 2773 observations and 4 variables.

NOTE: PROCEDURE FREQ used (Total process time):

      real time           0.02 seconds

      cpu time            0.03 seconds

Thanks,

Mur

Freq wants to put the BY variable and the table variables in the output data set. Since you have STDATE on both the by and table statements it thinks you want it in the data twice but it can only have one.

For the output requested you probably don't need the BY statement at all.
