Program Example40;
{ Program to demonstrate the MaxAvail function. }
Var
P : Pointer;
I : longint;

{ This will allocate memory until there is no more memory}

begin

GetMem (P,1000);
end;
{ Default 4MB heap is allocated, so 4000 blocks
should be allocated.
When compiled with the -Ch10000 switch, the program
will be able to allocate 10 block }
