Re: garbage collection

[Gregory Bourassa]

Mike,

How the heap is used differs from implementation to implementation of Prolog.  
You are 
correct in assuming that it usually has a relationship with compound terms.

The code you propose is exactly what will keep the heap clean during reading.

Make sure the semantics of readln/1 is to bind its argument with eof, in the 
Prolog you 
decide to use.   If it fails on eof then your code will not terminate.

Regards.
