to get it more concrete:

I don't think that there is a %sleep macro, so I tried

%let dummy=%sysfunc(sleep(5));

to let the execution sleep for 5 seconds at that location.
To use only %sysfunc(sleep(5)) is not a good idea, because that function
returns the seconds as result.

That should do it (don't know if 5 sec are ok, could be less or more...)

Simply

data _null_ ;
  s = sleep(60) ;
run ;

Depending on the environment, you may need to represent the value in
milliseconds.
