Ниже предлагается исправленный вариант программы.
program name;
uses crt;
var a:integer;
begin

if a<1703 then Writeln('Город не существовал')
else
if (a>=1703) and (a<1914) or (a>=1991) then Writeln ('Санкт-Петербург')
else
if (a>=1914) and (a<1924) then Writeln ('Петроград')
else Writeln ('Ленинград');
