Interesting that as a SAS beginner you chose to focus on CALL MISSING...

Either way, such information can you get yourself off  the shelf by a simple search, like this:

Without CALL MISSING, you would use slightly different tools to set a variable to a missing value.  For numerics:

sales=.;

For character variables:

name=' ';

With CALL MISSING, you don't need to know where a variable is character or numeric.  You can simply specify:

call missing(sales);

Also, CALL MISSING lets you mention many variables at a time, setting them all to missing, in a single statement.
