You can use an ALSO operator in a WHERE statement (or function). Use a series of WHERE statements instead of a single statement. The condition clauses are combined as if you wrote a single WHERE statement with the condition clauses ANDed together. For example,

proc print data = sashelp.class;
 title 'Teenage Boys';
 where Sex = 'M';
 where also Age > 12;

produces the same output that the following WHERE statement would:

where Sex = 'M' and Age > 12;

Note that the first WHERE statement can also use the ALSO modifier even if there is no prior WHERE statement:

proc print data = sashelp.class;
 title 'Teenage Boys';
 where also Sex = 'M';
 where also Age > 12;
