Do you mean something like this?
>> blort: [1 2 0 3 0 4 5 6 0 7]
== [1 2 0 3 0 4 5 6 0 7]
>> find-all: func [b [block!] v [any-type!] /local result] [
[ result: copy []
[ forall b [if v = b/1 [append result index? b]]
[ result
[ ]
>> find-all blort 0
== [3 5 9]
I used a block of numbers to save typing, but the principle
is the same IMHO.
HTH!
