    Can you explain the problem you are having? What does the program do wrong?
    How do you want to change what the program does?
    If you don't understand my answer, don't ignore it, ask a question.

    my problem is how to write file using notepad where the firstline is looping in one line like this
    07-12345-Wilson-Dacles-T.-February 1, 1995-male-lordwils02@gmail.com-taguig city:21-12345-Wilson-Dacles-T.-February 1, 1995-male-lordwils02@gmail.com-taguig city:0721-1234-Rhoan-Mariano-T.-February 1, 1995-male-@gmail.com-Taguig:2121-12345-Wilson-Dacles-T.-February 1, 1995-male-lordwils02@gmail.com-taguig:2121-12321-wilon-ddasa-a-January 1, 1995-male-lordwil0-bataan:

    and other looping is write every nextline like this:
    07-12345-Wilson-Dacles-T.-February 1, 1995-male-lordwils02@gmail.com-taguig city
21-12345-Wilson-Dacles-T.-February 1, 1995-male-lordwils02@gmail.com-taguig city
0721-1234-Rhoan-Mariano-T.-February 1, 1995-male-@gmail.com-Taguig
2121-12345-Wilson-Dacles-T.-February 1, 1995-male-lordwils02@gmail.com-taguig

    so the output of textfile should be is :
    07-12345-Wilson-Dacles-T.-February 1, 1995-male-lordwils02@gmail.com-taguig city:21-12345-Wilson-Dacles-T.-February 1, 1995-male-lordwils02@gmail.com-taguig city:0721-1234-Rhoan-Mariano-T.-February 1, 1995-male-@gmail.com-Taguig:2121-12345-Wilson-Dacles-T.-February 1, 1995-male-lordwils02@gmail.com-taguig:2121-12321-wilon-ddasa-a-January 1, 1995-male-lordwil0-bataan:
07-12345-Wilson-Dacles-T.-February 1, 1995-male-lordwils02@gmail.com-taguig city
21-12345-Wilson-Dacles-T.-February 1, 1995-male-lordwils02@gmail.com-taguig city
0721-1234-Rhoan-Mariano-T.-February 1, 1995-male-@gmail.com-Taguig
2121-12345-Wilson-Dacles-T.-February 1, 1995-male-lordwils02@gmail.com-taguig


    --- Update ---

    for example:
    When I Register or write a new account the output is:
    07-12345-Wilson-Dacles-T.-February 1, 1995-male-lordwils02@gmail.com-taguig city:
07-12345-Wilson-Dacles-T.-February 1, 1995-male-lordwils02@gmail.com-taguig city

    then, when I register or write again:
    07-12345-Wilson-Dacles-T.-February 1, 1995-male-lordwils02@gmail.com-taguig city:21-12345-Wilson-Dacles-T.-February 1, 1995-male-lordwils02@gmail.com-taguig city:
07-12345-Wilson-Dacles-T.-February 1, 1995-male-lordwils02@gmail.com-taguig city
21-12345-Wilson-Dacles-T.-February 1, 1995-male-lordwils02@gmail.com-taguig city

    Can you explain what the code does wrong? What is the problem with it that you want to change?
    You posted several lines of text but don't say what the problem is and what you want to change. You have to tell us what is wrong with the program now and what you want it to do differently.

    The posted code takes data for one line and writes that one line at the end of the current text file.
    How do you want to change that?
    If you don't understand my answer, don't ignore it, ask a question.

    I'm not sure that I fully understand what you're asking. Can you try to clarify your question by providing both more detail and more pertinent code?

    This is your fourth thread on the same issue. You should wait for someone to respond to your first thread instead of re-posting the same question.

    I agree. Stick with one thread, else you're not being fair to the volunteers who help on this forum.
