[REBOL] Re: Newbie questions

Hi Kai.
For "the most elegant way" I would direct you to Gabriele ;-).
A workable way would be:
given the ini file
name1="value1"
name2=640
name3=SVGA
Let's assume we are looking for the value of name3:
We need to convert the ini file into something that can be conveniently
processed under REBOL, for instance a block. The final expression could
look something like this:
select make block! replace/all read %IniFile.ini "=" " " 'name3
1. We read the contents of the file IniFile.ini
... read %IniFile.ini
The percent sign is needed to tell REBOL IniFile.ini is a file name.
'read returns a string.
2. Since we will want to use select (see help select for details) we
want to rid of the '=' signs and replace them by a space.
... replace/all ... "=" " "
(see help replace for details on replace/all)
3. We use the string returned by replace to create a block.
... make block! replace/all ...
4. Now we can retrieve the value associated with name3 by using select:
select make block! ... 'name3
Note that we must use the literal word 'name3 We cannot use name3,
since REBOL would believe it to be a word, and attempt to look up the
value of name3.
Hope this helps.
