In ANSI Lisp, is there a predefined function that will count the
number of occurences of a number/symbol/list within a list?

Thanks,

In Common Lisp there is "count", which should work for counting lists
within lists with ":test 'equal".

[Give someone a fish and feed him for a day.]

The function is called count.

[Teach someone to fish and you feed him for a lifetime.]

Try (apropos "COUNT" 'common-lisp).

Also try (describe 'count) and (documentation 'count 'function).

I prefer:

Build a man a fire and he is warm for a night.
Set a man on fire and he is warm for the rest of his life.
