    Post Loop Fanuc Oi

    Hi

    I'm new to the subject, and would like to create a one-repeat loop for a program like this, using IF, WHILE, GOTO.
    I'm work with a mazak VCP 400S.

    I want to use the coordinates used in the drilling to make a thread without having to repeat each one using IF or WHILE.
    I can use GOTO to return to block x-24.5 but I don't know how to tell it not to repeat again when it encounters GOTO again.
