i've seen your post on "webmasters corner" section, it was about that program where you need to duplicate lines. if you didn't already fixed something out, i could make you a fast and efficient dos program that would work on this algorhytm :
(file1.txt)
aa
bb
cc
- you insert that file into my prog-
(program generates - file2.txt)
aa aa
bb bb
cc cc
that's how it would work, if you are interested just reply me, and i will make that in 15 mins.
