Ou, surely. But it is new bug. When I used tp there was'n second
increase.
Also buf_count value is 10 and I have tried to add only 5 elements.
After
second startup the problems have begun.
Well, all I can say is check your code securely. The basic idea is good,
so it is likely the implementation.
I will try. May be there is some problem with index and memory in tp and
dos (dos emulation in NT) is unsecure.

Sorry, but I didn't understand what you ment exactly. You ment to use
ptr_buf
= P and then getmem(P) and for loop?
Instead of:
for i:=1 to cur_size do
buff_ptr^[i] := P^[i];
... do:
move(p^[1],buff_ptr^[1],(cur_size-1)*sizeof(p^);
Thanks, I will try.
Also, is your array really 1-based?
Hm... I didn't understand. I have such definitions of my array:
type dynamic_array = array[1..buf_count] of BusStation; //BusStation is
record with 4 strings
dynamic_array_ptr = ^dynamic_array;
var
list:dynamic_array_ptr; // it's my "dynamic array" with its size counter
list_count:Integer;
...
// How I use it:
for i:=1 to num_of_strings do
begin
if i > list_count then
add_mem(list,list_count);
I herd that there were problems with dos games: sometimes they started not
from the beginning, but from last time ending.
