function lsteamapp(appid,b)
	 if b == nil then b = false end
	 if b == true then print_text=true;
			   else print_text=false;
			   end

    local link = 'steam://run/'
    local RunCombination = link .. "" .. appid
    if(print_text==true)then print(RunCombination) end
    shellExecute(RunCombination)
end

-- usage = appid,optional boolean: if true -- prints what is being executed;
--lsteamapp(220) --lsteamapp(220,false) or --lsteamapp(220,true)
