   I'm not sure why you're asking this question in this thread.  
Recursion is a capability which _all_ Pascal implementations support, and 
the amount/level of recursion which TP/BP (or others) will handle is a 
function of the Stack.  These subjects have little to do with use of Real 
Memory - except that TP/BP limits the total amount of Stack which can be 
used to 64K - while the topic has been dealing with dynamic memory 
allocation...on the Heap.  Different things, really, and the programmer's 
use of recursion isn't really affected by the uses of the Heap.
   Your question seems based on a rather fuzzy understanding of what 
Pascal does and how it's used, I'm afraid...
