SAS, count variable

Given the following macro variable:

 %let var = name salary work;

I need to create a macro variable which has the number of the variables in the var. In this example, this newly created macro variable is equal to 3.

The basic concept here is using the COUNTW function. You can't use that directly in a macro variable assignment though (in a %let), but you can use %SYSFUNC to enable you to use it.

%let var_count = %sysfunc(countw(&var.));

Note there are no quotation marks or similar.
