Example

Program Example41;

{ Program to demonstrate the MemAvail function. }

Var  
  P, PP : Pointer;

begin
  GetMem (P,100);
  GetMem (PP,10000);
  FreeMem (P,100);
  { Due to the heap fragmentation introduced
    By the previous calls, the maximum amount of memory
    isn't equal to the maximum block size available. } 
  Writeln ('Total heap available    (Bytes) : ',MemAvail);
  Writeln ('Largest block available (Bytes) : ',MaxAvail);  
end.
