Pascal - Program Perkalian Matriks Ordo n x m dengan m x p

program Kali_Matrix;
uses wincrt;
var
   a,b,c : array [1..50,1..50] of integer;
   i,j,k,n,m,p : integer;
begin
     clrscr;
     writeln('Ukuran matrix A');
     write('Baris : '); readln(n);
     write('Kolom : '); readln(m);
     writeln;
     writeln;
     writeln('Ukuran matrix B');
     writeln('Baris : ',m);

     writeln;
     for i:=1 to n do
     for j:=1 to m do

Bila ada yang kurang harap di maklumi karena saya juga masih belajar,,,
