[REBOL] bitset actions?

From: Rebolinth:nodep:dds:nl at: 24-Dec-2003 22:39

Hallo All, Is there a way to 'pick on bitsets? Im looking for a way to select a range or a single character from a bitset on a specific location, but i can emagine that the 'bitset does not do serie handing the way series does. I thought bitsets where smaler (and quicker using parsing) , but i can emagine using a normal string range would even do the trick as quick as well? (which im currently using in my program) A simple example to visualise the problem.. ;;; example 1 t1: charset [ #"a" - #"q" #"x" - #"z" ] t2: charset [ #"A" - #"Q" #"t" - #"v" ] pick t2 index? find t1 #"x" ;;; example 2 t1: charset "KHEWWKJEWBLKUWEOFBIYTEWQFBOYTEWUEQIUFBITWQUFB" t2: charset "QWEIRLUYQWIURYLQWUYREOIWQUYROIQUWYEOIRUYWQEOI" pick t2 index? find t1 #"x" The above does not work ... But is there a way to compare 2 bitsets ranges with eachother, using parse perhpas?, like the above, but without ..union..etc...?
