Hello,

> it returns the unique values in this block....
> but if I want the repeated ones???? in this particular case "1" ????
>> u: unique o: copy b: [1 2 2 2 3 4 1 1 1]
== [1 2 3 4]
>> head foreach i u [remove find o i]
== [2 2 1 1 1]
; b is the block, o (output) is a copy of that block,
; u is a 'unique'd copy of the same block
; foreach item of the unique block, remove that item from the output block
;(once only). That leaves, therefore, only the duplicate values in b.
; show me the head of the output series (o).
Anton.
