This is an extension of my first post ...

I am also working on a predicate where I am trying to count the even numbers
(chars) in a number.
i.e. count_even(243,C) returns C = 2.

I can't think how to "loop" over the number char by char, that's why the
recusrion is needed - so I tried to work it out by saying the number is a
list, hence the first post.

Please note - I have used the Java forum extensively and those who seek help
with assignments are frowned upon - these q's are not assignments. I am
trying to create some teaching materials (high shcool level) and teach
myself some Prolog at the same time. I have found a few interesting
"questions" from various www sites and am now working on them, but I need
help (too entrenched in an imperative mindset).

yours thankfully
Darren
