Для пяти введённых действительны чисел найти максимальное и минимальное. Помогите в паскале

Вот код:

var a,b,c,d,e,min,max:integer;

begin

Read (a,b,c,d,e);

if (a>b) and (a>c) and (a>d) and (a>e) then max:= a;

if (b>a) and (b>e) and (b>c) and (b>d) then max:= b;

if (c>a) and (c>b) and (c>d) and (c>e) then max:= c;

if (d>a) and (d>c) and (d>b) and (d>e) then max:= d;

if (e>b) and (e>a) and (e>d) and (e>c) then max:= e;

if (a<b) and (a<c) and (a<d) and (a<e) then min:= a;

if (b<a) and (b<e) and (b<c) and (b<d) then min= b;

if (c<a) and (c<b) and (c<d) and (c<e) then min:= c;

if (d<a) and (d<c) and (d<b) and (d<e) then min:= d;

if (e<b) and (e<a) and (e<d) and (e<c) then min:= e;

Writeln ('Минимальное число: ',min);

Writeln ('Максимальное число: ',max);

end.
