How to select a variable with "_XX" by using proc sql?

[ybz12003]

Hello:

I would like to use proc sql to create table by using the following variable?  Please let me know how to make SAS recognize the variable names.  

proc sql;
create table library.text2 as
select HAVARTH3 _BMI5CAT _SMOKER3

from library.test1;

The SAS log showes the following error massage:

ERROR 22-322: Syntax error, expecting one of the following: a quoted string, !, !!, &, (, *, **, +,
',', -, '.', /, <, <=, <>, =, >, >=, ?, AND, AS, BETWEEN, CONTAINS, EQ, EQT, FORMAT,
FROM, GE, GET, GT, GTT, IN, INFORMAT, INTO, IS, LABEL, LE, LEN, LENGTH, LET, LIKE, LT,
LTT, NE, NET, NOT, NOTIN, OR, TRANSCODE, ^, ^=, |, ||, ~, ~=.

ERROR 76-322: Syntax error, statement will be ignored.

Please help.  Thanks.

SQL requires commas whenever you specify a list:

proc sql;
create table library.text2 as
select HAVARTH3, _BMI5CAT, _SMOKER3

from library.test1;

Sql requires commas to separate elemnt like list of variables:

proc sql;
create table library.text2 as
select HAVARTH3,
           _BMI5CAT,
         _SMOKER3
from library.test1;
quit;
