Would the seek command help?
Presumably it would move the file pointer to the specified point without
having to load the entire file into RAM.
If you knew your lines were shorter than a given length, say 1000 chars,
you could so something like:
open file tFile for append
seek relative -1000 in file tFile
repeat
read from file tFile until cr
if it is not empty then
put it after tBuffer
else
delete last line of tBuffer
write tBuffer to file tFile
end if
end repeat
close file tFile
This is off the top of my head to test before using on real data. ;)
