To quote change.txt included in the 2.7.6 SDK distribution: "Note that
<w>EXTRACT now returns a series of the same type as the source series." =
This
is technically true for binary series, but it still does not work as one
should have the right to expect intuitively. Let us take a simple binary
series, created by to-binary "1 2 3 ", thus #{312032203320}. One should
expect <extract #{312032203320} 2> to result in #{313233} just like =
<extract
"1 2 3 " 2> results in "123". However this is not the case: the result =
is
#{343935303531}. This is because each element of a binary series is of =
type
integer, and although the first element of #{312032203320} is 49, the =
result
of <append #{} 49> is not #{31} but #{3439}, in other words 49 is =
implicitly
converted to string! before the append. However, if one computes =
<copy/part
#{312032203320} 1>, one gets #{31}, and <append #{} #{31}> yields #{31} =
as
it should. In other words, in the source of extract, it suffices to =
replace
<pick block pos> by <copy/part at block pos 1>, in order to obtain a =
result
which is similar to that for strings.What do you think? Rudolf W. MEIJER mailto:[EMAIL PROTECTED] http://users.telenet.be/rwmeijer/ -- To unsubscribe from the list, just send an email to lists at rebol.com with unsubscribe as the subject.
