Male 	White
Male 	Black
Female	White
Female	Black
Female 	White
Female 	White
Female	.	 
Male	.	 
.  		White
.  		Black
;

 RUN;
 
 DATA DATA_0;
 SET DATA_0;

 	IF SEX = MALE AND RACE = WHITE THEN SEX_RACE = "MALE WHITE";
	ELSE IF sex = MALE AND RACE = BLACK THEN SEX_RACE = "MALE BLACK";
	ELSE IF sex = FeMALE AND RACE = BLACK THEN SEX_RACE = "FEMALE BLACK";

	/*ELSE IF BMI >= 25 THEN BMI_CAT = "OVERWEIGHT";
	IF BMI = . THEN BMI_CAT = " "; */
 RUN;

Data data_0;
	Input sex$	race$;
cards;
Male 	White
Male 	Black
Male 	White
Male 	Black

;

 RUN;
 
 DATA DATA_0;
 SET DATA_0;

	ELSE IF sex = MALE AND RACE = BLACK THEN SEX_RACE = "MALE BLACK";
	ELSE IF sex = FeMALE AND RACE = BLACK THEN SEX_RACE = "FEMALE BLACK";

 RUN;

I get the following error!

Can someone help me?

When you refer to the value of a character variable, you have to put it in quotes:

if sex='Male' then ......

Other notes:

• Case is important.  This would fail:  if sex="MALE' then ......
• You probably typed in tabs as part of the data, instead of spaces.  If so, you would need to replace the tab characters with spaces. 

Tabs are OK in the programming statements, but not in the data.

Tabs have nothing to do in a program imho. Spaces only belong in code.

Lol

Glad we are on the same page and sanity prevails! 😄

Thank you Astounding! you are right! I should have put all the values under inverted commas. Moreover, male and female, black and white should be in lower case as in the data.
