You realize 3 will not divide 44 evenly ?

What have you got so far ?

[jeanpaulw]

Hi, yes , let say that i have a file with 45 LINES or 33 LINES.

[keskiverto]

1. Read three lines
2. Write one line
3. Repeat from 1

Keskiverto is 100% correct but I thought I'd add a little more detail.

Ask for input file name
Ask for output file name

Open file, while good
loop
Read line 1 output with ()
Read line 2 output with {}
Read line 3 output with []
end loop
