[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...?
Regards,
Norman.
