My main concern is whether I can implement the following dynamic
allocation of memory space for graphs, images, and matrices.
type
  graph_type(num_points:integer)=array [0..num_points-1] of real;

var
  xg:graph_ptr;
  i:integer;
begin
  for i:=100 to 200 do begin
    new(xg,i);
    dispose(xg,i);

Here we are creating arrays of integers of increasing size and disposing
of them. I started moving to FPC a few years back, only to find that
this dynamic functionality is not available.
Hi Kevan,

Dynamic arrays are available in FPC.

I would have thought that your program stub above could be written for
FPC something like;-

program A;

type
  graph_type = array of real;

var
  xg:graph_type;
  i:integer;

begin
  for i:=100 to 200 do
  begin
    setlength(xg,i);
    xg := nil;
  end;
end.

Peter
