It does:

>> difference "abcd" "cdef"
== "abef"

and rebol seems prefer {"} over "^""

[REBOL] bug ? Re:(3)

Hi Daniel,

what exactly _are_ file1 and file2? You are calling them files,
but are you sure they're files? As I see it, the are not. Lessee
what happens here ...

REBOL/Core 2.3.0.4.2 24-Jun-2000
Copyright 2000 REBOL Technologies.  All rights reserved.
>> difference file1 file2
** Script Error: file1 has no value.
** Where: difference file1 file2
>> difference %file1 %file2
== "12"
>> difference "file1" "file2"
== "12"



>> difference file1 file2
== {:1235!"%?RUGHCFT89}

So, 'file1 'file2 are normally just words, that can't be
used for difference, %file1 %file2 work just like strings,
as expected, cause %file1 is a series. 

And now, about my "magic", it was just:

>> file1: {:12374576$!"-&)(/%&)%%%} file2: {)?&/$&()RUGHCFTR(/87694} 

And this may be, what you've done:

file1: read %somefile
file2: read %some_other_file

And then difference worked on the _contents_ of the files,
which were read as series, and referenced as 'file1 / 2


regards,

Ingo

it works as described, not as you expect:

>> difference %file1 %file2
== "12"

what gets compared is the %file1 and %file2 as the series, not
their contents.

Hello,

Isn't the following consistent?

Mike.


 read %a.txt
== {1
2
3
4
5
6}
>> read %b.txt
== {1
2
3
5
6}
>> difference read %a.txt read %b.txt
== "4"
