proc sort giving error message

[Geoghegan]

Hello,

I have a dataset with a variable I made called CVD which has 0 or 1 as options only in SAS9.4. This is technically my outcome of my analysis but as a way to display the data I would like to make two boxplots of the exposure values (il6) by CVD value. So I would like one boxplot to be the il6 values for CVD=0 and one for CVD=1. I thought to do this I would just create a copy of my dataset, sort it by CVD, and then use the boxplot function, below: 

data stats.adjusted4;
set stats.adjusted3;
run;
proc sort stats.adjusted4;
by descending CVD;
run;
proc boxplot data=stats.adjusted4;
plot log_il6*CVD/ cboxes=black;
run;

However, when I ran the proc sort it gave me this error message and I can't figure out what it wants me to do:

291  proc sort stats.adjusted4;

I've used proc sort before for things like sex and assumed I could with this too. If anyone could help I would greatly appreciate it!

please update the code to below, to use 'data='

proc sort data=stats.adjusted4;
by descending CVD;
run;
