Dear experts,

Let’s say I create a new variable in the c++ interface:

PlTerm t ;

When I print this variable, e.g. by

cout \<\< (char\*) t \<\< endl ;

It’s name is something like \_1620. Can I give it a different name? I need it for pretty printing only, so, in principle, I can unify it with some atom ‘X’ and all good, but maybe there is something more elegant.

Best wishes

Matthias

Ups. I see that the pretty names aren’t visible inside prolog, just from write\_term. Ok, case closed.
