Hi,

Can someone help me, I think I got a serious problem.
Here it is:
During the compiling of a program I'm working on, I
get the message:

     Error 49: Data segment too large.

The message is clear, but so isn't the solution.
BTW I'm using TP6 (no Windows or whatsoever).

If someone knows a solution, I'm eager to hear/read it.

Thanks in advance for any help,

The reason of the problem is that you have declared all static variables
e.g.
var aReal : real;

In a pascal program (or may be even all MS-Dos programs) the size of the data
segment is limited to 64 kB (i.e. the size of one memory paragraph).

Try using pointers (alias dynamic variables} instead. These will be allocated
on the heap which is as large as you want (within the limits of your
computers RAM).

example:
type
  Preal = ^real;    {define a pointer to a real}

var
  aReal : PReal;  {this will be your dynamic variable}

...
New(aReal);       {allocate space on the heap}
aReal^ := 9.23;    {you can now assign a value to your variable}
...
Dispose(aReal); {when you don't need it anymore, free the memory}

I suggest you do some reading about pointers. Good luck,

var
  Dots: array[0..99] of record
    x, y, z : word;
   end;

begin
  for i := 0 to 99 do
    Dots[i].x := 42;
end.

change it to this:

type
  TDots: Array[0..99] of record
    x, y, z : word;
   end;
  PDots : ^TDots;

var
  Dots : PDots;

begin
  new (Dots);  { DON'T forget to new() your pointers!!! :) }
  for i := 0 to 99 do
    Dots^[i].x := 42;
end.

If you don't need all your data at any given time, you can dispose() your
various structures when they're not needed any more.  Just remember: any
reference to the structure as a variable now has a ^ between the variable
name and the structure.

I suggest you read up on pointers, data structures, etc. in the various
manuals.  The manuals are actually pretty useful, at least if you're a
beginner.

Another solution is sending an e-mail to Borland
telling then that they should at last develop
a new Borland Pascal for DOS without such
silly restrictions.
