Targets: MS-DOS, OS/2, Win32

System Unit

Creates a new dynamic variable and sets a pointer variable to point to it.

Declaration:

  procedure New(Var P: Pointer);

Remarks:
New determines the amount of heap to allocate by the size of the typed variable pointed to by P. To reference the new variable, use P^. If New finds that there is an insufficient amount of free heap, a runtime error is generated.

Note that the size of heap variables is not limited to 66,535 (64K) bytes.

Example:

{$ifndef __CON__}
  This program must be compiled as console application only
{$endif}
var
  P: ^String[16];
begin
  New(P);
  P^ := 'How are you?';
  Writeln(P^);
  Dispose(P);
end.
