Yes, there is some debugger support for this: If you are using the command-line version of Eclipse, check out the debugger's v-command (var/term modification skip). If you are using tkeclipse, you should have a look at the "display matrix" facilities, and the related "observe term" options in the tracer. Finally, if you have already upgraded to Eclipse 5.4, you can try the new Visualisation Tools (see separate manual). > > I want to send this output to a file so I can analyse it.

You just write ?- my_goal(...) onto_file "my_log_file". and the output from my_goal(...) will be written to the file. -- Joachim Schimpf / phone: +44 20 7594 8187 IC-Parc, Imperial College / mailto:J.Schimpf@ic.ac.uk London SW7 2AZ, UK / http://www.icparc.ic.ac.uk/eclipseReceived on Thu Jul 04 21:47:11 2002
