Selecting two samples from a roster randomly

hi,
I have gone through the public example of random selection posted by you.
https://designer.mysurvey.solutions/questionnaire/details/7e6f99e3744e4ed9b56879482d99be04/chapter/8ae67f9587324f00bd24d35a71526833/group/8ae67f9587324f00bd24d35a71526833

I have a roster of all establishments in a village/town.
I want to know what has to be done (syntax) to select two samples from the above roster
regards
