I'm not exactly sure what you're looking for, but you could use the
'load function.
>> strings: {"string a" "string b" "string c"}
== {"string a" "string b" "string c"}
>> load strings
== ["string a" "string b" "string c"
]
>> foreach [a b c] load strings [print [a b c]]
string a string b string c
The next thing you have to do is decide on the format of the file.
There are various ways you could do it, here is one -
a: "string a"
b: "string b"
c: "string c"
write/append %string-text.txt remold [a b c]
write/append %string-text.txt remold ["first" "second" "third"]
write/append %string-text.txt remold ["baz" "boo" "foobar"]
Now look at the file
>> read %string-text.txt
== {["string a" "string b" "string c"]["first" "second" "third"]["baz"
boo
"foobar"]}
It is seperated into blocks of three strings, which is very easy to
use. The 'load function will do all the conversion for you. You can
also use the 'save function instead of write/append, which is basically
the reverse of 'load.
>> foreach group load %string-text.txt [foreach [a b c] group [print [a b c]]]
string a string b string c
first second third
baz boo foobar
Something that you should note is that Rebol seems to have some trouble
with some strings that have speech marks and curly brackets in them.
