Thank you Patrick,

In fact, I want to estimate which amount of memory I can allocate on the
heap without disturbing too much other applications. Which is the most
pertinent "free" value for starting calculus? The value from your FreeMemory
procedure or the value from GetHeapInfo? Is the memory in "low" and "high"
parameters allocatable? I suppose it's reserved for the stack, isn't it?

Regards.
