REBOL 3 Functions: select

select  series  value  /part  length  /only  /case  /any  /with  wild  /skip  size  /last  /reverse

Finds a value in the series and returns the value or series after it.


series [series! port! map! object! none!]

value [any-type!]


/part - Limits the search to a given length or position

length [number! series! pair!]

/only - Treats a series value as only a single value

/case - Characters are case-sensitive

/any - Enables the * and ? wildcards

/with - Allows custom wildcards

wild [string!] - Specifies alternates for * and ?

/skip - Treat the series as records of fixed size

size [integer!]

/last - Backwards from end of series

/reverse - Backwards from the current position

find   switch  


Similar to the find function, but returns the next value in the series rather than the position of the match. Returns NONE if search failed.

The /only refinement is evaluated for a block argument and is ignored if the argument is a string.
