Hi Brett, On Thursday, July 24, 2003, 7:44:19 AM, you wrote: BH> collect: func [ BH> {Collects block evaluations, use with For, Repeat, etc.} BH> block [block!] BH> /init result "Initialise the result series."

Anyway, this is a great idea! Regards, Gabriele. -- Gabriele Santilli <[g--santilli--tiscalinet--it]> -- REBOL Programmer Amiga Group Italia sez. L'Aquila --- SOON:
