Is there a reason you want to use column pointers? Why not simply:

data dsn;
input id visit_date :date11.;
format visit_date date11.;
datalines;
001 05-may-2019
002 05-jun-2019
003 05-jul-2019
004 05-aug-2019
005 05-sep-2019
;
run;

Format and informat names must be one word, not two. Remove the extra blank:

format visit_date date11.;
Informat visit_date date11.;
