Turn macro variable into a number

[sleretrano]

I want to use a macro variable in a WHERE condition in a PROC SQL, but I need to to be evaluated as a number because Var3 below is numeric.

%let horizon=201606:

PROC SQL;
CREATE TABLE CTX AS
SELECT Variables
FROM Table1 T1
LEFT JOIN Table2 T2 ON (T1.Var1=T2.Var1)
WHERE T2.Var3 le %EVAL(put(&Horizon.,6.));
QUIT;

How can I go about this?

Macro variables are text not really char/numeric. They do literal text replacement. 

The following will work:

Where t2.var3 LE &horizon;

If it doesn't work you may have a type mismatch and most likely var3 is numeric with a date format?

It did work, thanks. I hadn't thought of trying the most simple thing.
