Well, would this work...
a-list: read/lines %original-file.txt
new-list: sort a-list
write/lines %new-file.txt new-list
If not, then there's something I'm not understanding...
Hmmm. Unless you want to read a line in at a time for some reason?
In that case, open a port for reading your file. ie...
a-port: open/lines %original-file.txt
You can then access the file via the port as if it was a normal
series. ie...
a-list: copy [] ; Block to put lines in.
forall a-port [
append a-list first a-port
]
Then close the port...
close a-port
The lines will now be in the a-list block and can be sorted and saved
as with my first example.
