As the ever-concise toby points out, CALL MISSING will do what you want, but
will operate on a variable list:

call missing(a,b,c,d,...,z);

If your variables are in an array, or are in the dataset in a fashion to be
able to take advantage of any of the variable list options, then you can use
that as well, in combination with the OF keyword.

call missing(of var:) for example for VAR1, VAR5, VAR8.
