Re: [Info-gnuprologjava] How to dereference a VariableTerm by it's name

[Juan Galán]

Hello again

Thank you for your answer. It's exactly what I was looking for. I saved lot 
of time thanks to this.
I have another question:
I get an exception that i guess it is a stack overflow problem. I've tried 
executing the same prolog program in Swi-Prolog and in GNU-Prolog. In 
swi-prolog it works properly but in GNU-Prolog I get a stack overflow error. 
As GPJ is based on GNU-Prolog it seems to be a stack overflow problem. This 
happens while running a prolog implementation of Dijkstra Algorithm for big 
graphs.

My question is if it is possible to modify the stack size in GPJ.

This is the exception I get:
