[mjaywant]

Hi,

I am New to SAS & practicing on SAS university Edition. while practicing for If-then-else statement, I am getting below error;

"ERROR 388-185: Expecting an arithmetic operator.

ERROR 200-322: The symbol is not recognized and will be ignored."

Below is the complete code from editor:

data work.newfile;
 set sashelp.heart;
 Where Smoking_Status='Non-smoker';
 if Weight>100, then Weight_Status='Underweight';
 if Weight<100, then Weight_Status='Overweight';
 Keep Status Sex Height Weight Weight_Status Smoking Smoking_Status;
run;

proc contents data=work.newfile;
run;

proc print data=work.newfile;
run;

Please help on these.  

I tried all possible solutions from my side.

There shouldn't be a comma after the expression Weight>100, 

if Weight>100, then Weight_Status='Underweight';
 if Weight<100, then Weight_Status='Overweight';

correction:

if Weight>100 then Weight_Status='Underweight';
else  if Weight<100 then Weight_Status='Overweight';
