When I run query human(Who). on the below .pl file
human(ann).
human(george).
human(mike).
I only get back Who = ann .
Instead of
Who = ann ;
Who = george ;
Who = mike.
Am using prolog 6.6.6. How do I get it to show the full list?
The answer you got was the following. Do you note the space before the dot?
Who = ann .
^ SPACE!!!
This space means: The query was aborted. Maybe you typed return. Or maybe you have a somewhat illconfigured terminal.
To better check this, try:
?- X = 1 ; X = 2 ; X = 3.
There you should get all three answers, too. If not, it is definitely your terminal
