Попробуйте такой вариант: тут все byte заменены на Integer. Может быть, прокатит.
Код:
const
MaxWord = 200;
delimiter = [' ',',','.','(',')',':','?','!'];
type
TBook = array[1..MaxWord] of string; // type of word output array
Procedure GetWords(line: string; var words: TBook; var count: Integer); // Fragmentation of string to words according to delimiter
var
back,pos,m: integer;
begin
pos:=1;
m:=0;
while pos <= length(line) do
begin
while (pos <= length(line)) and (line[pos] in delimiter) do pos:=pos+1;
if pos <= length(line) then
begin
back:=pos;
while (pos <= length(line)) and not(line[pos] in delimiter) do pos:=pos+1;
m:=m+1;
words[m]:=copy(line,back,pos-back);
end;
end;
count:=m;
end;
var
book,txt: TBook;
shifr,posit: array[1..MaxWord] of Integer;
i,j,k,n,q,key: Integer;
st: string;
f: text;
b: boolean;
begin
assign(f,'D:\kkk.txt');
reset(f);
while not eof(f) do
begin
readln(f,st);
GetWords(st,book,n);
end;
close(f);
writeln;
writeln('Code book read successfully...');
for i:=1 to n do write(book[i]+' ');
repeat
writeln;
writeln(' < MENU >');
writeln(' 1 - encode text');
writeln(' 2 - decode text');
writeln(' 3 - exit');
writeln;
write('Enter the item number: ');
readln(key);
case key of
1: begin
write('Enter the text: ');
readln(st);
writeln('Encoded text: ');
GetWords(st,txt,k);
for i:=1 to k do posit[i]:=0;
b:=false;
for i:=1 to k do
begin
b:=false;
repeat
j:=1;
repeat
if (txt[i]=book[j]) and (j>posit[i]) then
begin

posit[i]:=j;
shifr[i]:=j;
for q:=i+1 to k do
if txt[q]=txt[i] then posit[q]:=j;

writeln;
end;
end;

end.
